Radius of an arc - Sector - Mensuration problem solver

length of the arc of a sector is 66 cm and the sector angle is 45 degree. Find its radius.


Length of the arc = 66
Sector angle = 45
Radius of the Arc (r) = (360/D) * (1/(2 * Pi) * l
Radius of the Arc (r) = (360/45) * (1/(2 * (22/7))) * 66
Radius = 84
Radius of Length of the Arc (r) = 84 units
