What is the value of the angle \(108^\circ\) in circular measure (radians)?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → \(\displaystyle\frac{3\pi}{5}\)
Circular measure is the angle in radians, and \(180^\circ=\pi\) radians. So degrees are changed to radians by multiplying by \(\frac{\pi}{180}\).
\(108^\circ\displaystyle=108\times\frac{\pi}{180}=\frac{3\pi}{5}\)
