Question

Calculate the perimeter of a sector of a circle of radius 14cm, where the sector angle is 60 0 . Take π =22/7

Answer 1

Answer:

Given,

Radius(r) = 14 cm

Ф = 60 degree

π = 22/7

Perimeter of a sector  = θ/360×2π(r)+2*r

                                    = 60/360 * 2 * 22/7 * 14 + 2* 14

                                    = 1/6 *88 + 28

                                    = 14.667 + 28

                                    = 42.667 cm
