Question

What is the Volume of the cylinder, in cubic ft, with a height of 18ft and a base diameter of 10ft? Round to the nearest tenths place.

Answer 1

if it has a diameter of 10, then 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 1413.7~ft^3`
