Aspherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters. which expression gives the volume of the sphere, in cubic centimeters?

Start with the volume equation for a sphere:

V=4/3pi•r^3

The dimensions of the cylinder allow for a sphere with a diameter of 20 centimeters, so the radius of this sphere will be 10 centimeters. Substituting this into the equation:

V=4/3pi•(10)^3

or the uppermost right answer (B).
