Question

Janine inflated a ball to a radius of 18 cm and another ball to a radius of 12 cm.

How much greater was the volume of air in the larger ball than the smaller ball?

Use 3.14 to approximate pi. Round to the nearest hundredth if necessary.

Answer 1

Answer:since your are looking for the volume of the ball, the answer would be 17182.08

Explanation:

Answer 2

Volume of a ball = (4/3)πr³

When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³

the volume of air in the larger ball is 17182.08 cm³ greater than smaller ball
