Answered by admin @
Answer:
The ratio of the surface areas 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
