1. The problem statement, all variables and given/known data A circular pizza of radius R has a circular piece of radius R/2 removed from one side. Clearly the center of gravity has moved from C to C' along the x-axis. Show that the distance from C to C' is R/6. (Assume that the thickness and density of the pizza are uniform throughout.) 2. Relevant equations 3. The attempt at a solution I started off with taking the smaller circle as the negative mass. xCG = (m1 x1 - m2 x2) / (m1 - m2) But I do not know what to do after this. Please help asap. Thanks.
