π in radians
Step-by-step explanation:We know that:
180° is equivalent to π (in radians).
Therefore, to convert 345° into radians, all we have to do is cross multiplication as follows:
180° .................................> π (in radians)
345° .................................> ??
345° = (345*π) / (180°) =

π in radians
