The answer:

The statement of the problem does not state your question. Based on the title of your submission I assume you want to find the volume of a basketball with a radius of 12 cm.

Volume of a sphere:

v = volume = ?
r = radius = 12 cm

v = (4/3)*π*r³

v = (4/3)*π*(12)³
v = (4/3)*π*(1728)

v = 7238.23 cm³


the final answer is: 7,238.23 cubic centimeters

------------------------------------

However, this is not the end of the story.

The measurement for the radius is 12 cm.

The number 12 has only two significant digits.

Technically, the final answer should have only two significant digits as well. The final answer should be rounded so that it shows only as many significant digits as the least accurate number used in the calculation.

The final answer should be rounded to: 7200 cm³ (7,200 cubic centimeters).
