Question

A cylinder has a radius of 10 m and a height of 8 m.

What is the exact volume of the cylinder?

A. 187 m
B. 807 m
C. 160 m
D. 800 m

Answer 1

`D`

Explanation:

`Volume`
`of`
`cylinder` ≈
`\pi`
`radius^(2)` ×
`height`

`Volume` ≈
`\pi` ×
`10^(2)` × 8
`800\pi`

`so`
`it`
`is`
`D`

Answer 2

D. 800 m

Explanation:

Volume of a cylinder is πr²h

Here, r=10 h=8

so the volume is

=π x 10² x8

=π x 100 x 8

=800m

The answer is 800m
