Question

The area of the quadrant of a circle of radius r is​

Answer 1

$\huge{\blue{\boxed{\boxed{\boxed{\boxed{\bold{\red{Answer:}}}}}}}}$

that is, pi (π) multiplied by the radius squared (r2). Now, to calculate the area of a quadrant, divide the area of a circle by 4 (as four quadrants make a circle). We get, Area of a quadrant, A= (πr2)/4 Square units

Answer 2

Answer:

Perimeter of quadrant of a circle =  

4 1  ×2π×r+2r

=  2 πr  +2r

=  2 r [π+4]
