Question

Joey has a beach ball with a radius of 20 cm. What volume of air will it hold when fully inflated? [Round to nearest tenth.] A) 83.8 cm3 B) 251.4 cm3 C) 1676.2 cm3 D) 33,493.3 cm3

Answer 1

Answer:

Option D. $33,493.3\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the sphere (beach ball) is equal to

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

we have

$r=20\ cm$

substitute

$V=\frac{4}{3}\pi (20^{3})=33,493.3\ cm^{3}$

Answer 2

Answer:
V=4/3*3.14*20^3
V=4.1867*8,000
V=33,493 cm^3 ans.
