Question

the radii of two sphere are in the ratio 2 : 3 then the ratio of their respective volumes is​

Answer 1

Answer:

Let the radii of two circles be 2x and 3x respectively. Then volume of first circle = 22/7*2x*h.

Volume of 2nd circle = 22/7*3x*h.

Therefore ratio of their volumes = 22/7*2x*h:22/7*3x*h.

Therefore

22/7*2x*h/22/7*3x*h=2:3.

Therefore ratio of their volumes = 2:3.
