Since r = h, we can substitute that into the equation <span>V = pi * r^2 * r = pi * r^3 </span>
<span>Since we know the volume, we can put that in too. </span> <span>64 pi = pi * r^3 now let's divide both sides by pi. </span> <span>64 pi/pi = pi * r^3/pi </span> <span>64 = r^3 </span> <span>cuberoot(64) = r </span> <span>cuberoot (2^6 )=r </span> <span>4 = r</span>
