The moment of inertia of a solid cylindrer about its axis of ratation is `(MR^(2))/(2)`. What is the value if the radius of gyration of the cylinder about this axis ?

Explanation

To find the radius of gyration of a solid cylinder about its axis of rotation, we can follow these steps:

### Step 1: Understand the Moment of Inertia
The moment of inertia \( I \) of a solid cylinder about its axis of rotation is given by the formula:
\[ I = \frac{1}{2} M R^2 \]
where \( M \) is the mass of the cylinder and \( R \) is the radius of the cylinder.
