Expert Solution
Step 1

There are many ways to prove the volume of the right circular cylinder using calculus. The method of polar coordinate is one of them.

Consider a right circular cylinder of radius r and height h as shown in fig shown below. A very infinitesimally small element which is at distance ρ from the polar axis, making angle angle dθ with its polar axis and having thickness dz , so the cross section area dA=ρdθ×dρ
