Question

a cone and a cylinder are of same height the radii of their bases are in the ratio of 1:2 find the ratio of their volumes

Answer 1

v=3.14*(r)^2*h
as the height is same the ratio of the radius is to be taken into account
so,
V/V1=1/4

Answer 2

we know that the volume is cylinder is
$\pi \: {r}^{2} h$


and the volume is cone is
$\frac{1}{3} \pi \: {r}^{2} h$


so let the radius of the cylinder and cone be 2x and xb respectively.


so the ratio of the volume will be.

3πr^2h /πr^2h
3r^2/r^2
3X4/1

12:1(Ans).
