Question

The volume of two spheres are in the ratio 64:27.The ratio of their surface area is​

Answer 1

Answer:

the ratio off the surface area is 16:9

Step-by-step explanation:

To find the ratio of the surface areas, first we have to find the surface areas with their volumes.

Radius of big sphere = R

Radius of small sphere = r.  

Volume of bigger sphere

Volume of smaller sphere

Given,

Volume of bigger sphere : Volume of smaller sphere = 64 : 27.

Surface area of bigger sphere

Surface area of smaller sphere

Hence, Surface area of bigger sphere: Surface area of smaller sphere =  

Thus, the ratio of their surface areas = 16 : 9
