Question

If radius and height are equal for a cylinder,cone and hemispere are same,the ratio of their volume will be------

Answer 1

the ratios are

πr^2h : π/3 r^2h : 2π/3 r^3
= πr^3 : π/3 r^^3 : 2π/3 r^3
I expect you can take it from there. Just factor out the common values and clear the fractions as needed.
