Heya mate....

we all know very well that protactor is a semicircled figure...

Thus its perimeter will be equal to the perimeter of a semicircle + diameter of it i.e. 

{ (π×r) + 2r } unit (Generally it should me in cm)

here r= radius....

Protractor is a semicircle. so perimeter of its curved part is half of 2πr i.e, πr.
now the lower part of protactor is the length of a diameter of circle having radius r. so, its length is 2r.
thus, perimeter of a protactor is πr + 2r.

option C is correct.
