The area of the quadrant of a circle whose circumference is 22 cm, will be :

3.5 cm2 10 cm2 38.5 cm2 9.625 cm2

9.625 cm2

Circumference of a circle = 2πR The circumference of a circle = 22 (Given) 2πR = 22 2 × \(\frac{22}{7}\) × r = 22 r = \(\frac{7}{2}\) We know that, Area of a quadrant =\(\frac{1}{4}\) πr2  = \(\frac{1}{4}\) × \(\frac{22}{7}\)  × \(\frac{7}{2}\) × \(\frac{7}{2}\)  = \(\frac{77}{8}\)  = 9.625 cm2
