The radius of a sphere X is 3 inches, and radius of sphere Y is 9 inches. How many

times larger is the volume of sphere Y compared to sphere X?

The volume of the sphere Y is 27 times the volume of the sphere X

Step-by-step explanation:

Sphere X:

Radius of sphere X = 3 inches

Volume = (4/3) π (27)

Sphere Y:

Radius of sphere Y = 9 inches

Volume = (4/3) π (729)

Volume of sphere Y / volume of sphere X = (4/3) π (729) / (4/3) π (27)

= (729) / (27)

= 27

The volume of the sphere Y is 27 times the volume of the sphere X
