Question

100 POINTS What is the volume of this cone? Use 3.14 for N

Answer 1

68.64pi or 215.64

Explanation:

So lets go over the formula for volume of a cone.(note if needed for future problems, this can also be used for pyramid.)

The formula is:

r^2*h*pi*1/3

Or:

`(r^2*h*\pi )/(3)`

We know that the radius is 6.

We also know that 5.72 is height.

Lets plug these in:

`(6^2*5.72*pi)/(3)`

Now square the 6.

`(36*5.72*pi)/(3)`

Now multiply the 36 by 5.72.

`(205.92*pi)/(3)`

Combine the 205.92 and pi.

`(205.92\pi )/(3)`

Finally, divide by the 3.

`68.64pi`

This is your answer!

Hope this helps! :D

Answer 2

D. 215.5

Explanation:

The formula for this equation is V= 3.14 x
`6^(2)` x 5.72 ÷ 3

Plug all of that into your calculator and you should get 215.5296.

From here just round to the nearest tenth and you'll be left with answer D. 215.5
