V+=+4%2F3xpixr%5E3 where r is the radius, which

is 1%2F2 the diameter.  Since the diameter is 100mm, the

radius is 1%2F2 of 100mm or 50mm.  So we substitute

50mm for r in the equation:

V+=+4%2F3xpir%5E3

V+=+4%2F3xpix%2850mm%29%5E3

V+=+4%2F3xpix50mm%2A50mm%2A50mm

V+=+4%2F3xpix125000mm%5E3

For pi some people use 22%2F7 even though that 
is technically inaccurate but it is accurate to three 
significant figures. 
So we'll use it:

V+=+4%2F3x22%2F7x125000mm%5E3

Using a calculator, that comes out

523809.5238mm%5E3 

but since it is accurate only to three significant
figures we round it to:

524000mm%5E3 or if you prefer 524000cubic_millimeters.

Did you want to convert that to cubic centimeters or milliliters?

If so post again.
