Find the radian measures corresponding to the following degree measures:(i) `25^o` (ii) `- 47^o30prime` (iii) `240^o` (iv) `520^o`

Explanation

To convert degrees to radians, we use the formula:

\[ \text{Radian measure} = \text{Degree measure} \times \frac{\pi}{180} \]

Now, let's solve each part step by step.
