180° = π radians
→ 45° = π × 45°/180° radians = π/4 radians

45 degrees are pi/4 radians. You can verify this with a unit circle.
45 degrees (+/- 180k degrees for any integer k) or pi/4 radians (+/- pi*k radians for any integer k).
45 degrees or 0.785398163. The first part is pi radians divided by 4, not quite the same thing.
The formula for converting radians to degrees is the given angle in radians multiplied by (180 degrees / pi), so in this case, 7 pi radians would be equal to 1260 degrees. (By the way, the greek letter pi isn't spelled with an e).
since 1 radian = 180/π degrees 210 degrees = 210/180 * π radians = 7/6 * π radians = 3.665191429...
