```							The moment of inertia of a uniform semicircular wire of mass M and radius r about a line perpendicular to the plane of the wire through the center is''Mr²''. Explanation ⇒ According to the question, the mass of the wire is at a distance r away from the axis. We know that the moment of the Inertia in such case will be given by the formula,  Moment of Inertia = Mv²where, m is the mass and r is the Perpendicular distance.

```							Dear student Using Parallel Axis Theorem of MII1=I+mx^2where I1= Moment of inertia about centre=mr^2and I= Moment of inertia about centre of mass which is requiredx=2r/π(distance between centre of mass of wire and its geometrical centre) THUSI=I1−m(2r/π)^2I=mr^2[1−4/π^2]
