Question

a cylinder has a base diameter of 18 inches and a height of 2inches.What is its volume in cubic inches,to the nearest tenths place?

Answer 1

`508.9\ in^(3)`

Explanation:

we know that

The volume of a cylinder is equal to

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

In this problem we have

`r=18/2=9\ in`

`h=2\ in`

substitutes

`V=\pi (9^(2))(2)=162\pi\ in^(3)`

Assume
`\pi =3.1416`

`V=162\pi\ in^(3)=162(3.1416)=508.9\ in^(3)`
