Answer:
volume of cylinder =π r^2 h
Step-by-step explanation:
Volume is proportional to square of radius and linearly proportional to height of cylinder. if h kept constant radius is doubled volume increases by 2^2 ie it becomes 4 fold. If radius trebled volume will be 9 times the original keeping h constant
if you keep h constant increase radius 4 times volume increases by 4 times only
v/πr^2h is constant =π like circumference/diameter =π
