Question

ariel is filling a giant beach ball with air. the radius of the beach ball is 30 cm. what is the volume of air that the beach ball will hold? either enter an exact answer in terms of π or use 3.14 for π. cm³

Explanation:

Step1: Recall sphere volume formula

Volume $V = \frac{4}{3}\pi r^3$

Step2: Substitute radius $r=30$ cm

$V = \frac{4}{3}\pi (30)^3 = \frac{4}{3}\pi \times 27000 = 36000\pi$

Step3: Calculate with $\pi=3.14$

$V = 36000 \times 3.14 = 113040$

Answer:

36000π cm³ or 113040 cm³
