What is the radius of a sphere with volume sixty four thousand cubic centimeters
A: 10.52 cm
B: 11.52 cm
C: 12.52 cm
D: None of these

Volume equals four thirds pi r cubed. Solve r cubed equals 64000 times three divided by four pi. That is 48000 divided by pi. Cube root yields approximately eleven point five two. Mental math uses pi near three point one four. Calculators give close agreement. Therefore choose eleven point five two centimeters as the radius.
