Question

The volume of two spheres are in ratio of 64:27. Find their radii if the sum of their radii is 21 cm.

Answer 1

v1/v2 = 64/27
= r1^3/r2^3
r1/r2 = 4/3
r1+r2 = 7x = 21
x = 3
rad1 = 12
rad 2 = 9

Answer 2

Answer:

3467

Step-by-step explanation:

v1/v2 = 64/27

= r1^3/r2^3

r1/r2 = 4/3

r1+r2 = 7x = 21

x = 3

rad1 = 12

rad 2 = 9
