Question

Sergio has two similar cylindrical pots, Pot A and Pot B. The radius of Pot A is 15 inches, and the radius of Pot B is 3 inches. What is the ratio of the volume of Pot A to the volume of Pot B?

15:3
45:9
125:1
5:1

Answer 1

125 : 1

Explanation:

given 2 similar objects with ratio of sides a : b , then

ratio of volumes = a³ : b³

here

ratio of pot A : pot B = 15 : 3 = 5 : 1

ratio of volumes = 5³ : 1³ = 125 : 1
