Question

A beach ball has a diameter of 10 inches. What is the volume of air contained inside the beach ball? Use 3.14 for pi. Round your answer to the nearest hundredth. Group of answer choices 314.00 cubic inches 452.23 cubic inches 500.75 cubic inches 523.33 cubic inches

Answer 1

Answer:523.33 cubic inches

Explanation:

π=3.14

Diameter=10

radius=diameter ➗ 2

radius=10 ➗ 2

radius =5

Volume of sphere=4/3 x π x radius x radius x radius

Volume of sphere=4/3 x 3.14 x 5 x 5 x 5

Volume of sphere=(4x3.14x5x5x5) ➗ 3

Volume of sphere=1570 ➗ 3

Volume of sphere=523.33

Answer 2

Explanation:

Volume of sphere = 4/3 *pi * r^3

= 4/3 * 3.14 * 52

= 523.33
