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

Answer 2

Option D.
`33,493.3\ cm^(3)`

Explanation:

we know that

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

`V=(4)/(3)\pi r^(3)`

we have

`r=20\ cm`

substitute

`V=(4)/(3)\pi (20^(3))=33,493.3\ cm^(3)`
