Question

What is the volume of a cylinder with base radius 4 and height 5?

Either enter an exact answer in terms of m or use 3.14 for t and enter your answer as a decimal.

Answer 1

251.2 units³ ; 80π units³

Explanation:

Volume of a Cylinder is:
`V=\pi r^2 h`

'r' is the radius.

'h' is he height.

The cylinder has a base radius of 4 units and the height 5 units.

Using 3.14 for Pi:

`V=3.14*4^2*5\\V=3.14*16*5\\V= 50.24 * 5\\\boxed {V=251.2}`

The approximate volume is 251.2 units³.

In terms of pi:

`V=\pi 4^2*5\\\rightarrow 4^2=16\\V=\pi 16*5\\V=\pi 80\\\boxed {V=80\pi}`

The exact volume is 80π units³.
