Find the central angle ¥è of the sector with radius R and the arc length L.

Since the length of the arc is proportional to the magnitude of the central angle, the following proportional expression holds.

360 : 2*¥ð*R = ¥è : L

Thus, the center angle ¥è is :

¥è = 360*L / (2*¥ð*R)


*** Âü°í¹®Çå[References] ***

¥è = 360*L / (2*¥ð*R)
