Solution (By Examveda Team) Clearly, We have r = 3 cm and h = 4 cm ∴ Volume = 1 3 π r 2 h = ( 1 3 × π × 3 2 × 4) c m 3 = 12 π c m 3. Noumaan Malik : 2 years ago. They have said that to rotate around 3 cm side. That means to make a cone we have to make a round circle around 3 cm line. Seema : 5 years ago. How do we know that 3 will be Option A
