What is the volume of a cone that has a height of 7 mm and a radius of 3 mm?Use 3.14 to approximate pi and express your answer in hundredths.

Answers

Answer 1

Answer: So we want to know the volume V of a cone with a height h=7 mm and of radius r=3 mm rounded to the nearest hundreth. We need the formula for the volume of a cone: V=(1/3)*pi*r^2*h. Now we simply input the numbers and get: V=65.94 mm^2 and that is rounded to the first hundreth.

7.2x = - 14.4..........................

Answers

Answer:

x = -2

Step-by-step explanation:

Step 1: Write equation

7.2x = -14.4

Step 2: Divide both sides by 7.2

x = -2

Step 3: Check

Plug in x to verify it's a solution.

7.2(-2) = -14.4

-14.4 = -14.4

Answer:

x = -2

A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 12 cm long and 4 cm wide. The diameter of each semicircle is the width of the rectangle. What is the area of bookmark ? Use 3.14 for pie

Answers

So you know that the are of a rectangle is Length x width, so that part is simply 12x4, which =48 sq cm.
To find the area of the two ends of the bookmark, two semicircles make one circle, so you can just find the area of one circle. The formula for the area of a circle is (3.14) x r². Because the diameter of the circle is the same as the width of the rectangle, half of the 4cm is the radius (2cm).
Area of Circle= (3.14)x(2²)=12.56 cm sq.
Total area = Area of rectangle + Area of Circle
TA= 48 + 12.56
TA= 60.56 sq cm

What is the length of leg s of the triangle below?

Answers

Hey there!

There are a few ways to do this, but I'll give you the one I can explain best.

This is a right triangle. We know this because one of the angles is 90º.

The lengths of the sides of the right triangle can be represented by the following equation:

a² + b² = c²

We already have the values for a and c, c being the hypotenuse.

3² + b² = (√18)²

Let's square a and c.

9 + b² = 18

Subtract 9 from each side of the equation.

b² = 9

To find the final value for b, find the square root of each side of the equation.

b = 3

Your answer is 3, or option D.

Hope this helps!
