The formula for the lateral area of a right cone la=pirs, where r is the radius of the base and s is the slant height of the cone. which are equivalent equations?

Answers

Answer:

$\pi r √(r^2+h^2)$

Step-by-step explanation:

Given that there is a cone with radius r and slant height s.

We know that lateral surface area of the cone is

= $\pi r s$

Alternately if instead of s, h is known we can write this in terms of h also.

Consider the right triangle formed by slant height, height and radius of the cone.

Using Pythagorean theorem we have

$s^2=r^2+h^2$

Or $s=√(r^2+h^2)$

Hence lateral surface area of the cone

= $\pi r √(r^2+h^2)$

The GDP is $11,465.2 billion. The population is 249,793,675. Find the per capita GDP.

Answers

Answer: $ 45898.68

Step-by-step explanation:

Given: Population = $249,793,675$

GDP = $11,465.2 billion

Since we know that 1 billion = 1,000,000,000

Therefore, GDP = $11,465,200,000,000

Also, the per capita GDP is calculated by :-

$\text{per capita GDP}=\frac{\text{GDP}}{\text{Population}}\n\n=(11,465,200,000,000)/(249,793,675)\n\n=45898.6801808\approx\$45898.68$

Hence, the per capita GDP = $ 45898.68

it would be 45898.68 $ for the capital gdp

In a class, 22 students have been on a plane, 28 on a train, 23 on a boat, 15 on a plane and train, 20 on a train and boat, 14 on a plane and boat, 12 on all three, and 1 on none of them. How many students are in the class?

Answers

Answer:

37 students are in the class

Step-by-step explanation:

There are 8 regions which the most inclusive clue is the inner one with 12.

"14 on a plane and boat" so we fill the intersection with plane and boat with 14-12=2
"20 on train an boat" 20-12=8 in the intersection
"15 on plane and train" = 15-12 = 3

now we look at this:

"22 students have been on a plane" 22 - (2+12+3) = 5 on the plane
"28 on a train" 28 - (12+8+3) = 5 on the train
"23 on a boat" 23-(12+8+2) = 1 on the boat

Just add up all the 8 numbers in the regions:

12+2+8+3+5+5+1+1=37

What is the slope of the equation for y=9-1.5x

Answers

$The\ slope-intercept\ formula:y=mx+b\n\nm\to the\ slope\nb\to\ y-intercept\n------------------\n\ny=9-1.5x\ny=-1.5x+9\n\n\boxed{The\ slope\ m=-1.5}$

This is called slope-intercept form. It is when a linear equation is written y=mx+b.
The m is the slope (rise over run or rate of change) and the b is the y-intercept (where this line crosses the y-axis).
So Think of rewriting this equation as:
y=-1.5x+9
Looks like y=mx+b doesn't it.
This means -1.5=m and thus the slope is -1.5.

A pizzeria makes brick-oven pizzas that are shaped like long rectangles with semi-circles at two ends. The pizzas come in three different sizes, which are measured by the longer side of each rectangle: 14 inches, 18 inches, and 29 inches. All of the pizzas are 10 inches wide, so the semi-circles at the ends have diameters of 10 inches, too. What is the area of each pizza? Use 3.14 for ? , and round your answers to the nearest tenth if necessary.

Answers

Answer:

Area of pizza whose longer side is of length is 14 inches = 218.5 $inches^(2)$

Area of pizza whose longer side of rectangle is 18 inches=258.5 $inches^(2)$

Area of pizza whose longer side is of length is 29 inches = 368.5 $inches^(2)$

Step-by-step explanation:

Given A pizzeria makes brick-oven pizzas that are shaped like long rectangles with semi-circles at two ends. The pizzas come in three different sizes, which are measured by the longer side of each rectangle: 14 inches, 18 inches, and 29 inches. All of the pizzas are 10 inches wide, so the semi-circles at the ends have diameters of 10 inches. we have to find the area of each pizza.

First, let us find the area of pizza whose longer side of rectangle is 14 inches

Area of 2 semicircles whose diameter is 10 inches

$=2((1)/(2)\pi r^(2))=\pi r^(2)=3.14* 5 * 5 = 78.5 inches^(2)$

Length = 14 inches

Breadth = 10 inches

Area of rectangle = $length * breadth$

= $14* 10=140 inches^(2)$

∴ Area of pizza whose longer side is of length is 14 inches = Area of rectangle + area of 2 semicircles

=140+78.5=218.5 $inches^(2)$

Now, let us find the area of pizza whose longer side of rectangle is 18 inches

Length = 18 inches

Breadth = 10 inches

Area of rectangle = $length * breadth$

= $18* 10=180 inches^(2)$

∴ Area of pizza whose longer side is of length is 18 inches = Area of rectangle + area of 2 semicircles

=180+78.5=258.5 $inches^(2)$

Now, let us find the area of pizza whose longer side of rectangle is 29 inches

Length =29 inches

Breadth = 10 inches

Area of rectangle = $length * breadth$

= $29* 10=290 inches^(2)$

∴ Area of pizza whose longer side is of length is 29 inches = Area of rectangle + area of 2 semicircles

=290+78.5=368.5 $inches^(2)$

Final answer:

To calculate the area of pizzas shaped like rectangles with semi-circular ends, we calculate the area of the rectangle and adjacent semi-circles separately then sum both. The rectangle's area is calculated as length times width while the semi-circle area is calculated as half of (pi*radius^2).

Explanation:

The area of a pizza that's shaped like a long rectangle with semi-circles at the ends can be calculated by first looking at the rectangle and then the semi-circles. For the rectangles, we use the formula for the area of a rectangle that is, length multiplied by width.

For the 14 inch pizza, the rectangle part:
Area = Length x Width = 14 x 10 = 140 square inches

The area of the semi-circle can be calculated as Area=1/2πr². The diameter is given as 10. So, the radius (r) will be half of the diameter, which is 5. Therefore, Area of each semi-circle = 1/2 x π x 5² = 1/2 x 3.14 x 25 = 39.25 square inches. The combined area of two such semi-circles will be = 39.25 x 2 = 78.5 square inches.

Adding the area for the rectangle and the semi-circles, the total area of each pizza will be 140 + 78.5 = 218.5 square inches.

Following these same steps, we can calculate the areas for the 18 inch and 29 inch pizzas.

706,286 rounded to the nearest ten thousand

Answers

the answer should be 710,00

Answer:

The number rounded to the nearest ten thousand is 710,000.

Step-by-step explanation:

We have the number 706,286. It is required to round this number to the nearest ten thousand.

1 - Unit.

10 - Ten

100 Hundred.

1,000 Thousand

10,000 Ten Thousand.

We need to round to the nearest number multiples of 10,000.

There are two simple rules to round numbers:

1- If the next number is equal or higher than 5, you should increase in 1 the previous number.

2- If the next number is less than 5, you can delete all the next numbers.

Analyzing the number 706,286 we can note that the number after 0 ten thousand is 6, as it is higher than 5, we should increase one unit.

706,286 rounded is

710,000.

Finally, we can conclude that the number rounded to the nearest ten thousand is 710,000.
