Question

7. What is the volume of a cylinder with a radius of 5and a height of 3?A. 30mB. 45mC. 75mD. 120m

Answer 1

Given

`\begin{gathered} r=5 \\ h=3 \end{gathered}`

The formula of the volume of a cylinder

`Volume\text{ of a cylinder=}\pi r^2h`

Substitute the given to the volume

`\begin{gathered} Volume=\pi*5^2*3 \\ Volume\text{ =75}\pi \\ Volume=\text{ 235.62 unit}^3 \end{gathered}`

The volume of a cylinder with a radius of 5 and a height of 3 is

`235.62\text{ unit}^3`
