Question

what is the volume of a cylinder of base radius 7 cm and height 12cm?

Answer 1

πr^2h = π x 7^2 x 12 = 1847.2 cm^3 (ans)

Answer 2

volume of cylinder = $\pi$ r2 h 
base radius=7cm
height=12cm
hence,volume of cyliner=$\pi$ r2 h
                                   22/7x7x7x12
                                   1848 cu cm
