Question

Michael has a ball that has a radius of 3 inches and Patrick has a ball that has a radius
of 9 inches. How many times bigger is the volume of the larger ball?

Answer 1

Answer:

27 times bigger

Step-by-step explanation:

V(sphere) = 4/3πr³

Michael:  4/3π3³ = 4/3×27π or 36π

Patrick:  4/3πr³ = 4/3πx9³ or 4/3x729π or 972π

36π to 972π is 1 : 27
