Question

Volume of two Spheres are in the ratio 64:27, then the ratio of their surface area is?​

Answer 1

Answer:

Volume of two Spheres are in the ratio = 64:27

4/3πr³/4/3πr'³ = 64/27

4/3πr³/4/3πr'³ = 64/27r/r' = 4/3

ratio of surface area of two spheres

= 4πr²/4πr'²

= r²/r'²

= 16/9

required ratio = 16:9 ^_^

hope this will help you
