Formula for a sphere: 4/3 * pi* r³

when the ball is fully inflated, the radius is 6.3 in

substituting r = 6.3

4/3 * pi * (6.3)³

= 1047.39 in³

Best of Luck! :)

Hello!

A beach ball is shaped as a sphere. You're trying to find the volume of a sphere.

$Formula: (4)/(3) \pi r^3$

r = 6.3
6.3³ = 6.3 × 6.3 × 6.3 = 250.047

(4)/(3) * 250.047 = (1000.188)/(3) = 333.396

333.396 × 3.14 = 1,046.9(rounded)

Answer ⇒ 1,046.9 inches
