A 25m long string cover the circular plate in form of a quadrant of a circle. find the area of the quadrant
----------------
If it covers it, you need to know the thickness of the string.
If it surrounds it, then:
r + r + 2*pi*r/4 = 25
r*(2 + pi/2) = 25
r = 50/(4 + pi)
-----------
You can work that out.
