D Correct answer
Explanation

To convert degrees to radians, multiply by pi/180. Thus, 720 * (pi/180) = 4pi. Therefore, a = 4.

AI explanation

Using the angle conversion formula, pi radians equals 180 degrees. To find the radian measure, multiply 720 degrees by the conversion factor pi divided by 180 degrees. The degrees cancel out, leaving 4 pi radians, which shows that the value of a is 4.
