r=12cm

The volume of a sphere is equal to 43 times Pi π times the radius cubed.

43⋅π⋅(radius)3

Substitute the value of the radius r=12 into the formula to find the volume of the sphere. Pi π is approximately equal to 3.14.

43⋅π⋅123

Combine 43 and π.

4π3⋅123

Raise 12 to the power of 3.

4π3⋅1728

Factor 3 out of 1728.

4π3⋅(3(576))

Cancel the common factor.

4π3⋅(3⋅576)

Rewrite the expression.

4π⋅576

4π⋅576

Multiply 576 by 4.
