Math.PI β€” degrees to radians

πŸ“– Usage Example
// Pi β€” ratio of circumference to diameter
Math.PI       // β†’ 3.1415926535...
2 * Math.PI   // β†’ 6.2831... (full circle in radians)

Use Math.PI when calculating circle circumferences, areas, or converting between degrees and radians.

Math.PI

Convert degrees to radians: radians = degrees Γ— (Math.PI / 180).

Challenge: Use Math.PI to convert common degree values to radians.

πŸ’‘ Hints (2)
  • β€’ Multiply degrees by Math.PI / 180 to get radians.
  • β€’ 180 degrees = Ο€ radians, so 360 degrees = 2Ο€ radians.
