Circumference of circle = 22 cm
=> 2*pi *r = 22
=> 2*22r/7 = 22
=> r = 22 * 7 /22 * 2
=> r = 3.5 cm
Area of quadrant = pi r^2 / 4
= 22*3.5*3.5 / 7 *4
= 22 *0.5 * 3.5 / 4
= 11*3.5 / 4
= 38.5/4
= 9.625 cm^2
=> 2*pi *r = 22
=> 2*22r/7 = 22
=> r = 22 * 7 /22 * 2
=> r = 3.5 cm
Area of quadrant = pi r^2 / 4
= 22*3.5*3.5 / 7 *4
= 22 *0.5 * 3.5 / 4
= 11*3.5 / 4
= 38.5/4
= 9.625 cm^2

tell fast
aage cancel kiya hai
22*7/22*2
22 cancel
ha toh kiya toh hai cancel aage
then 7*2
see
