find the circumference of a sector of angle 60, of a circle with radius 10cm

Circumference of a circle = 2*pie*r

        =   2 * 22/7 * 10

    = 62.85

circumference of a sector of angle 60 = circumference of circle / 6

  = 62.85 / 6

  = 10.476

  = 10.48 cm (approx.)

There is a formula to find the length of the arc formed by a sector....
Lengthof  an arc=θ/360 *2πr
So according to your question,
The circumference of the sector= 60/360 * 2π * 10
                                                             = 10.48 cm 
Hope this answer was helpful. Have a nice day. ;-)
