Question

The volume of the cylinder is given as v = πhr^2 (π = 22/7). If v = 198 cubic cm in the case of a roller; So what is the relation of its radius with height?

If h = 49 cm, then what is its radius?
If r = 3 cm., Then what is its height?

Please solve this problem in proportion method​

Answer 1

1. given h=49,v=πhr^2=198 in this information r=3/√7
2. given r=3,v=πhr^2=198 in this information h=7
