Question

A cylinder has a base radius of 10in and a height of 20in. What is its volume in cubic in, to the nearest tenths place?

Answer 1

6,283.2 in^3

Explanation:

The volume formula for a cylinder is V = (pi)r^2*h

and in this case r = 10 in, h = 20 in

so the volume of this cylinder is

V = 3.14159(10 in)^2*(20 in) = 6,283.2 in^3

Answer 2

6283.2

Explanation:

`V=\pi r^(2) h`

=
`=\pi *10^(2) *20`

=6283.18531

=6283.2(correct to the tenths place)
