Question

What’s the volume of this cone?

Answer 1

If you need a pi in your answer: 20.417
`\pi` (rounded to the nearest thousanth)

If you don't: 64.141 (rounded to the nearest thousanth)

Explanation:

The formula of the volume of a cone:
`V = \pi r^2(h)/(3)`

--> V = Volume, r = Radius, h = Height

In other words, the volume of the cone is the area of the circle x height x 1/3 x pi.

Since the radius of the cone is 3.5, you square that number.

--> (3.5)^2 = 12.25

The height is 5, so h/3 will be 5/3.

The volume =
`\pi` x 12.25 x 5/3

--> 20.416666...
`\pi`

--> 64.14085....

Answer 2

volume = (1/3) * π * r² * h

= 1/3* 22/7 * (3.5*3.5) * 5 ( 22/7 is the value of π)

=64.1
