Question

A cylinder has a radius of 12 m and a height of 9 m.

What is the exact volume of the cylinder?


108π m³

216π m³

972π m³

1296π m³

Answer 1

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=12\\ h=9 \end{cases}\implies V=\pi (12)^2(9)\implies V=1296\pi ~m^3`
