Question

Write six and seven hundred one-Thousands in standard form

Answer 1

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
