The radius of a sphere is 3 inches. which represents the volume of the sphere? a) 12π cubic inches b) 36π cubic inches c) 64π cubic inches d) 81π cubic inches

B)

Step-by-step explanation:

We know that the volume of a sphere is given by :-

, where r is radius of the sphere.

Given : The radius of the sphere = 3 inches

Then , the volume of the sphere will be :-

Hence, the volume of the sphere =

i'm not sure i quite understand, could you provide more information?

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
