Janine inflated a ball to a radius of 18 cm and another ball to a radius of 12 cm.
How much more air was in the larger ball?
Use 3.14 to approximate pi. Round to the nearest hundredth if necessary.
Enter your answer in the box.

cm³

Answer 1

We know, Volume of a Sphere = 4/3 πr³
v = 4/3 * 3.14 * 18³
v = 4.186 * 5832
v = 24,416.64 cm³

Volume of a Sphere = 4/3 πr³
v = 4/3 * 3.14 * 12³
v = 4.186 * 1728
v = 7234.56 cm³

Difference = 24,416.64 - 7234.56 = 17182.08

In short, Your Answer would be: 17182.08 cm³

Hope this helps!
