Answer 1

Answer:

this is your answer

Step-by-step explanation:

The perimeter of the sector of the circle will be equal to (2r + 200/r).

Area of a sector of the circle of angle x and radius r =xr²/2

Perimeter of the curved surface of the sector of the circle= xr.

Given, xr²/2=100 ⇒xr=200/r.

Perimeter of the sector of the circle = 2r + 200/r.
