Question

a cylindrical well has a tedious of 10 feet and a height of 15 feet. What volume of water will it take to fill the well

Answer 1

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=10\\ h=15 \end{cases}\implies V=\pi (10)^2(15)\implies V=1500\pi$
