Question

What is the volume of a can of beans with a height of 20cm and a radius 12cm use 3.14 to approximate pie EXPRESS YOUR ANSWER IN HUNDREDTHS ​

Answer 1

`\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ h=20\\ r=12 \end{cases}\implies V=\pi (12)^2(20)\implies V=2880\pi \\\\\\ \stackrel{\pi =3.14}{V=9043.2}\implies V=9043.20`
