I need the volume for 9,11,and 13

Answer 1

Answer:

Hey there!

Question 1

Let's use 3.14 for pi during this. It'll make it a lot easier.

The volume for a cone is $\pi r^(2) (h)/(3)$ .

The diameter of this cone is 17.6 inches. Since the radius is half the diameter, we can find the radius by dividing this amount by 2.

17.6 ÷ 2 = 8.8

The height of this cone is 23.4 inches.

Plug the values into the equation.

$\pi 8.8^(2) (23.4)/(3)$

Next, square 6.8 and divide 23.4 by 3. Also, replace the pi symbol with 3.14.

$3.14 * 77.44 * 7.8$

Multiply the numbers together.

The volume of this cone is approximately 1896.66 cubic inches.

Question 2

Finding the volume of a trapezoidal prism can be done by finding the are of the trapezoidal face and multiplying it by the depth.

Formula for finding the area of a trapezoid is $a = (1)/(2) h(b_(1) +b_(2) )$

The two bases are 10 and 34, and the height is 24.7 feet. Put these values into the equation.

$a = (1)/(2) 24.7(10 +34 )$

Add 10 and 34, then multiply it by 24.7 and 1/2.

a = 543.4

Multiply that value by 19, which is the depth of the figure.

The volume of the prism is 10324.6 cubic feet.

Question 3

The formula for volume of a triangular pyramid is v = 1/3ah, with a the area of the base and h the height.

The formula for the area of an equilateral triangle, which is the base, is $a = (√(3) )/(4) s^(2)$

The length of the side is 12, so we can square that to get 144.

Now multiply that by $(√(3) )/(4)$ to get the area of the base.

The area of the base is about 62.35 square meters.

The height of the pyramid is 20 meters. Plug that and the area of the base into the equation.

v = 1/3 x 62.35 x 20

Multiply the numbers together to get the volume.

The volume of the pyramid is approximately 415.67 cubic meters.

Hope this helps!

Answer:

22 miles

Step-by-step explanation:

15 is 1/4 of 60. 1/4 of 88 is 22.

Substitution for 4x+y=9 and y=-7

Answers

{y=-7

{4x+y=9 Substitute y.

4x+(-7)=9

4x-7=9 /+7

4x=16 /:4

x=4

Solution; (4; -7)

4x + y = 9

y = -7

Plug it in:

4x - 7 = 9

Add 7 to both sides:

4x = 16

Divide 4 to both sides:

x = 4

Plug this back into the equation:

4x + y = 9

4(4) + y = 9

16 + y = 9

Subtract 16 to both sides:

y = -7

So our solution is (4, -7)

209 divided 3. Please help! Sister got 6,911 I got 69.6 repeating. What is the answer. Thanks for the help.

Answers

Your sister made an error in calculating the answer, as 209 divided by 3 will not equate to a number bigger than the original number you start off with.

However, you are correct, as 209 ÷ 3 = 69.6 recurring.

the cafeteria has 45 square tables that can be pushed together to form one long table for the lacrosse team's banquet. Each square table can seat one person on each side. How many people can be seated at the banquet table?

Answers

Well, now the tables in the middle could hold 2 people each, while the ones at the ends 3 each. You have 92 people in total.

Since each table is 1 person so
45(1) =45 but since there are 2 more chairs at the side, it can sit up to 47

Answers

Answer:

The general equation is y=mx+b

the graph contains a vertex

the slop of the graph is constant and can be defined as rise over run

I would go for Y=mx+b

Which equation represents the graph of the linear function?

A. y= - 1/3x+1
B. y=-3x-1
C. y= 3x+1
D. y= -3x+1

Answers

We can rule out B and C immediately because they have positive slopes. The slope of the graph is negative.

The answer to the problem is D, because the slope is -3.
