  1. The formula for the volume of a sphere is: 4/3*π*r3
Your sphere has a diameter of 3 Cm. The radius is one half of the diameter, or 1.5 Cm.
This gives us: 4/3 x π x (1.5 x 1.5 x 1.5)
1. =1.3333 x π x (1.5 x 1.5 x 1.5)
2. =1.3333 x π x 3.375
3. =4.4998 x π or =4.5π
4. =4.5 x 3.1415
5. =14.13675
The volume of a sphere having a diameter of 3 Cm is 14.14 cubic Cm.

Ps- I'm not sure why, but when I post my answer it is put out of order. I apologize if this causes you any confusion. The answer is still the same.
