Question

What is the ratio of the volumes of two similar spheres, given that the ratio of their radii is 5:9?

PLEASE NEED ANSWERS

Answer 1

125 : 729

Explanation:

Given the ratio of the radii of 2 similar spheres = a : b , then

ratio of volumes = a³ : b³

Here the ratio of radii = 5 : 9 , thus

ratio of volumes = 5³ : 9³ = 125 : 729
