Question

What is the exact volume of a sphere whose diameter is 14 cm? Show your work.

Answer 1

1436.76

Explanation:

V=4

3πr3

Answer 2

radius= diameter/2

radius= 7cm

volume of a sphere =
`V=(4)/(3)\pi r^(3)`

so Volume = (4/3)*pi*7^3

7^3=343

4/3 = 1.3333333333

`(4*\pi*343)/(3)`= 4310.26512073 / 3

= 1436.75504024

Approx... 1436.76
