Question

a cylinder a hemisphere and a cone have equal base diameters and have the same height. Prove that their volumes are in the ratio 3:2:1.

please give correct solution
ans. is 732cm^3
please help dear guys its urgent.....​

Answer 1

Answer:

For cylinder,

Radius=Height=r

For hemisphere,

Radius=r

For cone,

Radius=Height=r

Volume of cylinder = πr
