Question

A phere has a diameter of 12 ft. What is the volume if the sphere? Give the exact value in terms of pi

Answer 1

Answer i took the test 288

Answer 2

if the diameter of it is 12, its radius is half that or 6.

$\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3} \begin{cases} r=radius\\ \cline{1-1} r=6 \end{cases}\implies V=\cfrac{4\pi (6)^3}{3}\implies V=288\pi$
