Question

The diameter of a billiard ball is approximately 6 cm. what is the volume? round your answer to the nearest whole number.

A. 113 cm3
B. 903 cm3
C. 25 cm3
D. 38 cm3

Answer 1

For this case we have that by definition, the volume of a sphere is given by:

`V = \frac {4} {3} \pi * r ^ 3`

Where:

r: It is the radius of the sphere

According to the data we have to:

`r = 3 \ cm`

Substituting we have:

`V = \frac {4} {3} \pi * 3 ^ 3\\V = \frac {4} {3} \pi * 27\\V = 36 \pi\\V = 113`

The option that best fits is option B.

Answer:

`V=113 \ cm^3`

The option that best fits is option B.
