Question

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

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.
