r=1.5meters

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=1.5 into the formula to find the volume of the sphere. Pi π is approximately equal to 3.14.

43⋅π⋅1.53

Combine 43 and π.

4π3⋅1.53

Raise 1.5 to the power of 3.

4π3⋅3.375

Combine 4π3 and 3.375.

4π⋅3.3753

Multiply 3.375 by 4.

13.5π3

Multiply 13.5 by π.
