Question

The volume of a sphere of radius 3 cm is

(A)
9x cm
(B)
18.t cm
(C)
27 cm
(D)
36 cm

Answer 1

3^3 = 27

27 * 3.14 = 84.78

84.78 * 4/3 = 113.04 is your answer.

Formula of volume of sphere is:

4/3 x π(3.14 or 22/7 whatever they tell you to use for pi) x r^3(your radius being cubed)

You get your radius by finding out what is half of your diameter or your given radius.
