25:9 will be the answer
Ratio of volume of two spheres = = 125 : 27
We know that volume of the sphere V =
Thus the ratio of the volume of spheres = = 125 : 27
⇒ = 5 : 3
We know that the surface area of sphere =
Thus the ratio of surface areas of two spheres
⇒ 25 : 9
Thus the ratio of areas of two spheres is 25 : 9
Thus option A is correct.
