Question

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

Answer 1

Answer:

9\16

Step-by-step explanation:

The volume of the sphere is proportional to the cube of the radius and surface area of the sphere is proportional to the square of the radius

v1\v2=64\27

r1\r2=3\4

a1\a2=r1\r2 square=3\4 square

=9\16
