r=0.7

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=0.7 into the formula to find the volume of the sphere. Pi π is approximately equal to 3.14.

43⋅π⋅0.73

Combine 43 and π.

4π3⋅0.73

Raise 0.7 to the power of 3.

4π3⋅0.343

Combine 4π3 and 0.343.

4π⋅0.3433

Multiply 0.343 by 4.

1.372π3

Multiply 1.372 by π.
