Question

The volumes of the two spheres are in the ratio 64 : 27. Find the ratio of their surface areas.

Answer 1

Given: Ratio of volume of two sphere=64:27

We know that, Volume of a Sphere = 4/3πr³

Let r₁ = radius of first sphere

r₂ = radius of second sphere

We know that, Surface area of sphere = 4πr²

Where π = 22/7

r = radius of a sphere

Therefore, ratio of surface area of two sphere is 16:9
