Question

A cylinder a cone and a hemisphere are of equal base and have the same height what is the ratio of their volume ?the crt answer and explanation will get brainlist​

Answer 1

Answer:

Now as we know that the height of the hemisphere is the radius of the hemisphere. Hence, the volume of the cylinder cone and hemisphere are in ratio 3 : 1 : 2.

Answer 2

Answer :-

Ratio between a cylinder, a cone and a hemisphere is 1 : 3 : 4

Given :-

r = h

(a) Area of cone:-

Vco = πr²h/3

Vco = πr³/3

(b) Area of Cylinder :-

Vcy = πr²h

Vcy = πr³

(c) Area of hemisphere :-

Vh = 4πr³/3

To find:-

Vco : Vcy : Vh = πr³/3 : πr³ : 4πr³/3

= 1/3 : 1 : 4/3

(×3) = 1 : 3 : 4
