Question

A cylinder has a diameter of 10 inches and a height of 18 inches what is the volume of the cylinder

Answer 1

if it has a diameter of 10, that means its radius is half that or 5.

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=5\\ h=18 \end{cases}\implies V=\pi (5)^2(18)\implies V\approx 1413.72~in^3`
