r=7cm

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=7 into the formula to find the volume of the sphere. Pi π is approximately equal to 3.14.

43⋅π⋅73

Combine 43 and π.

4π3⋅73

Raise 7 to the power of 3.

4π3⋅343

Combine 4π3 and 343.

4π⋅3433

Multiply 343 by 4.
