Question

A uniform circular disk of radius R = 36 cm has a hole cut out of it with radius r = 16 cm. The edge of the hole touches the center of the circular disk. The disk has uniform area density σ.

The horizontal center of mass of the disk with hole will be located: 
Write a symbolic equation for the total mass of the disk with the hole. 
Write an equation for the horizontal center of mass of the disk with the hole as measured from the center of the disk. 
Calculate the numeric position of the center of mass of the disk with hole from the center of the disk in cm.
