A circular hole of radius (a/2) is cut out of a circular disc of radius ‘a’ shown in figure. The centroid of the remaining circular portion with respect to point ‘O’ will be:
1
(10/11)a
2
\(\rm \left( \frac{2}{3} \right)a\)
3
\(\rm \left( \frac{1}{6} \right)a\)
4
\(\rm \left( \frac{5}{6} \right)a\)
