A quadrant is 1/4th part of a circle. We know that the area of a circle = πr².
So the area of a quadrant is 1/4πr².

Now the circumference of a circle = 2πr.
So, the length of the curved line of a quadrant = 1/4 x 2πr = 1/2πr
Now a quadrant consists of a curved line and two radii. So perimeter of a quadrant = 1/2πr + 2r

Hope that Helps !!
