Solution:

C = 22 cm as the circumference of the circle (given)

It’s noted that a quadrant of a circle is a sector that forms a 90° angle.

r be the radius of the circle

As C = 2πr = 22,

R = 22/2π cm = 7/2 cm

Therefore, the area of quadrant = (θ/360°) × πr²

Given here, θ = 90°

So, A = (90°/360°) × π r² cm²

= (49/16) π cm²

= 77/8 cm² = 9.6 cm²
