What is the distance, in radians, between 0 and 0=pie, sin0=0

We are asked to find the distance (in radians) between 0 and pi, and sin 0 to 0.

The value of pi in degrees is 180 degrees. In radians, its value is 3.1415. So from 0 to pi, the distance is simple 3.1415 rad. Since sin 0 is equal to 0, then its distance from 0 is also 0.
