Question

What is the volume of a cone with a radius of 3 feet and a height of 6 feet? Use 3.14 for pi. Round your answer to the nearest hundredth. A 18.31 ft B 40.25 ft C 56.52 ft D 60.34 ft

Answer 1

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\ -----\\ r=3\\ h=6 \end{cases}\implies V=\cfrac{\pi (3)^2(6)}{3}\implies V=18\pi$
