Question

Find the volume of each figure, round to nearest tenth.

Answer 1

Explanation:

The formula for the volume of a cone is;

V = 1/3 x pi x r squared x h

V = 1/3 x 3.14 x 4 x 12

V = 1/3 150.72

V = 150.72/3

V = 50.24 = 50.20 cubic ft

The volume is 50.20 cubic ft

The height is 12ft

the radius is 2ft

the diameter is 4ft

hope this helped!

Answer 2

Explanation:

On the assumption that the given information is that the height is 12ft and diameter is 4ft.

Then the radius which is half of the diameter is 2ft.

The volume equation of a cone with a circular base is

V=
`(1/3)\pi r^(2) h`= (1/3) *
`\pi`*
`2^(2)`*
`12` = 50.27 cubic feet
