How to calculate the moment of inertia of a semi-circular coil

How is the moment of inertia of a semi-circular coil calculated? Is there a formula for it?
The moment of inertia of a semi-circular coil can be calculated using the following formula: I = (1/2) * m * r^2, where I represents the moment of inertia, m represents the mass of the semi-circular coil, and r represents its radius. It should be noted that this formula is derived under the assumption that the centroid of the semi-circular coil is located at the center of the circle. If the center of mass is not at the center of the circle, the parallel axis theorem must be used for correction. The specific correction method is to multiply the square of the distance d from the centroid to the center of the circle by the mass m of the semi-disc coil, and add this value to the aforementioned formula. That is: I = (1/2) * m * r^2 + m * d^2. Hope this helps! .
