The diameter of a sphere is 21.6 cm. What is the sphere's volume? Round to the nearest tenth, if necessary.

NeX [460]

By definition, the volume of a sphere is:
$V = \frac{4}{3} (\pi) (r ^ 3)
$
Where,
r: sphere radio
Substituting values we have:
$V = \frac{4}{3}(3.14)(( \frac{21.6}{2} ) ^ 3)
$
$V = 5273.99424
$ Rounding the result to the nearest tenth:
$V = 5274.0 cm ^ 3
$ Answer:
the sphere's volume is:
$V = 5274.0 cm ^ 3$
