Question

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

Answer 1

By definition, the volume of a sphere is:

`V = (4)/(3) (\pi) (r ^ 3)`
Where,
r: sphere radio
Substituting values we have:

`V = (4)/(3)(3.14)(( (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`
