Which expression can be used to find the volume of the sphere?

A sphere with diameter 10 inches.
V = four-thirds pi r squared = Four-thirds (3.14) (5) squared
V = four-thirds pi r cubed = Four-thirds (3.14) (5) cubed
V = four-thirds pi r cubed = Four-thirds (3.14) (10) cubed
V = four-thirds pi r squared = Four-thirds (3.14) (10) squared

Answer 1

Second one:

V = four-thirds pi r cubed = Four-thirds (3.14) (5) cubed

Step-by-step explanation:

Radius = 10/2 = 5

Volume = (4/3) pi × r³

= (4/3) × pi × 5³

= (4/3) × 3.14 × 5³

Answer 2

`V = (4)/(3)\pi (5)^3`

Step-by-step explanation:

The formula to determine the volume of any sphere is:

`V = (4)/(3)\pi r^3`

In this case the diameter is given as:

d = 10 in.

The radius is half of that, hence:

r = 5 in.

`V = (4)/(3)\pi (5)^3`
