h, cone's height - UNKNOWN
r, cone's radius - KNOWN
v, volume of cone - KNOWN
FORMULA: v=%281%2F3%29h%2Api%2Ar%5E2

GOAL: Solve for h

PRINCIPLE: Multiplicative Inverse and Multiplication Property of Equality, usually recognized to be needed for use by site





%283v%29%2F%28pi%2Ar%5E2%29=1%2Ah%2A1%2A1
