Question
Find out the circumference of a sector whose radius is 7
cm and it makes the angle of 45° at the centre.ÂSolution
Radius = AO = BO = 7 cm Length of arc AB = Circumference of circle x angle of sector/360 = 2 πr x 45/360 = 2 x 22/7 x 7 x 45/360  = 5.5 cm Circumference of sector= arc AB + 2 x (radius) = 5.5 + 7 + 7 = 19.5cm
