12.5 wide, and 2.50 thick and has a 2.50--diameter hole drilled through its center such that the height of the hole is 2.50. The silicon in the plate is a mixture of naturally occurring isotopes. One of the those isotopes is silicon-30, which has an atomic mass of 29.97376 and a percent natural abundance of 3.10.
What is the volume of the plate? (Express the volume numerically in cubic centimeters.)
