**DrBob222**, Monday, September 5, 2011 at 1:56amConvert 2.80 inches to cm and take half (to find the radius), then V = pi*r^2*h.but pi*r^2 is the area; therefore, V = area*h. You can find the area from pi*r^2.

mass = volume x density. Substitute mass and density to find volume, Then substitute area into V = area*h and solve for h. That will give you thickness in cm.
