Question

what is the perimeter of sector of circle?

Answer 1

Hey mate !!

Here's the answer !!

Perimeter of sector = Sum of all sides.

We know that sector has radius and arc length as sides. Hence,

Perimeter = Radius + Radius + Arclength

=> Perimeter = 2 Radius + Arclength

Hope my answer helps !!

Cheers !!

Answer 2

area is 2 dimensional; All what's inside the circle. perimeter of the sector is the sum of the length of all its boundaries.thus the perimeter of the sector is L +2r units. 360×2 pie (r) + 2r that would be the length of the arc in the first part and twice the radius in the second part.
