A uniform disc A of radius 2m is cut as shown in the figure. The cut out is also a disc of radius 1m. O is the centre of gravity of disc A before cutting and O' is its centre of gravity after cutting. Find the distance between O and O'

2. Relevant equations

3. The attempt at a solution

I know how to find the CG of disc A and the CG of the new disc respectively..

But i don't know how to find out the CG of the newly cut disc A...

I don't know what approach should I use in this question

Can anyone help me please?
