"<span>The volume of a cylinder with height h and radius r is given by the formula below. V = Πr 2 h Complete the equation below by writing an equation equivalent to height, h, of a cylinder.
Please, instead of "</span>V = Πr 2 h," type V = pi*r^2*h: "pi times radius squared times h"
V
This can be solved for the height of a cyl.: h = ---------
pi*r^2
Use " ^ " to denote exponentiation, please.
