Question

a sphere,cylinder and a cone are of the same radius and same height.find the ratio of their respective volumes

Answer 1

Volume of a sphere = $\frac{4}{3} \pi r^{3}$

Volume of cylinder = $\pi r^{2}h$

Volume of a cone = $\frac{1}{3} \pi r^{3}$

Given that their radius and height is same.

So = Volume of sphere : Volume of cylinder : Volume of cone
     
     = $\frac{4}{3} : 1 : \frac{1}{3}$
