Question

The volume of one sphere is 27 times that of another sphere calculate the ratio of their surface area

Answer 1

Answer:

Let the radius of one sphere be=R and the radius of the another sphere be= r, then according to question, we have

The volume of one sphere = 27 times that of the another sphere

Hence, the ratio of their radii is:

Now, Surface area of the sphere having radius R=.

And surface area of the sphere having radius r=
