You are probably aware of the formula to calculate the volume of a sphere with radius r:\[V=\frac{ 4 }{ 3 }\pi r^3\]so you only need to convert the diameter (28 cm) to the radius, and put that value into the formula...

In a circle, the radius is half the diameter, so if the diameter is 28, the radius is 14. If you want to solve problems such as the above, this knowledge is rather essential, I'm afraid...
