To convert degrees to radians, we use the conversion factor \(\frac{\pi \text{ radians}}{180 \text{ degrees}}\).
To convert \(1540\) degrees to radians:
\[ \text{radians} = 1540 \times \frac{\pi}{180} \]
Now, we simplify the fraction:
First, divide \(1540\) by \(180\):
\[ 1540 \div 180 = \frac{1540}{180} = \frac{77}{9} \]
Thus,
\[ \text{radians} = \frac{77}{9} \pi \]
So,
\(\frac{77\pi}{9} \) radians is the final conversion.
The correct response is:
\[ \frac{77\pi}{9} \text{ radians} \]
