R/D = 3/6 = 0.5.

R/D = cg.
3/6 = .5.

X = 5R/6.
= 5(3)/6,
=2.5.

X is the distance of the centroid from the end in the question he asked distance of the centroid from centre.

Circle centre at 3 so;
3-2.5= 0.5 is the answer.

C.g of reminder from centre is R/6.
And from end is 7R/6,
So a/q.
From centre of plate R/6=3/6=.5

r/R = 1.5/3.0 = 0.5.
So,
C.G of the circle acts on the center of a circle.

On x - axis, X= R * 3 -r * 3/R * 2 - r * 2 = 3 * 3 - 1.5 * 3/3 * 3 - 1.5 * 2 = 3.5cm,
Hence distance of centre of gravity of remainder from centre of circle.
3.5 - 3 = 0.5.
