Write six and seven hundred one-Thousands in standard form

Since r = h, we can substitute that into the equation

V = pi * r^2 * r = pi * r^3

Since we know the volume, we can put that in too.

64 pi = pi * r^3 now let's divide both sides by pi.

64 pi/pi = pi * r^3/pi

64 = r^3

cuberoot (64) = r

cuberoot (2^6) = r

4 = r
