Radius of gyration of a body about an axis at a distance 6 cm from its centre of mass is 10 cm. Find its radius of gyration about a parallel axis through its centre of mass.

Explanation

To find the radius of gyration of a body about a parallel axis through its center of mass, we can use the parallel axis theorem. Let's go through the solution step by step.

### Step 1: Understand the Given Information
We are given:
- The radius of gyration \( r \) about an axis at a distance \( A \) from the center of mass is \( 10 \, \text{cm} \).
- The distance \( A \) from the center of mass to the axis is \( 6 \, \text{cm} \).

### Step 2: Write Down the Parallel Axis Theorem
