Question

Find the volume of a cylinder with a diameter of 28 meters and a height of 7 and one half meters. Approximate using tt =22 over 7.

Answer 1

if it has a diameter of 28, its radius is half that or 14.

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=14\\ h=7.5 \end{cases}\implies V=\pi (14)^2(7.5) \\\\\\ V=1470\pi \implies V=1470((22)/(7))\implies V=4620~m^3`
