Question

The arc of the sector is 1/8 of the circumference of the circle .Find the angle of the sector.

Answer 1

circumference of he circle = 2πr
arc of the sector= (x/360)*2πr

given that arc of the sector is 1/8 of the circumference of the circle.

(x/360)*2πr= (1/8)*2πr

x/360= 1/8
x= 360/8

x= 45°

hence angle of the sector= 45°
