Question

Question 92 (i) Radius of a cylinder is r and the height is h. Find the change in the volume if the height is doubled.

Solution

∵ Volume of a cylinder =πr2h where, h is height and r is radius of base of the cylinder. i) If height is double i.e. h=2×h=2h Then, its volume =πr2×2h =2πr2h Therefore, Volume became twice the original volume of the cylinder.
