The area of the quadrant of a circle whose circumference is 22 cm, will be;1. 3.5 cm22. 38.5 cm23. 10 cm24. 9.625 cm2

Answer» Correct Answer - Option 4 : 9.625 cm2

Given:

Circumference of the circle = 22 cm

Formula used:

Circumference = 2πr

Area of a circle = πr2

Area of the quadrant = (πr× 1/4)

r = Radius of the circle

Calculation:

2πr = 22

⇒ πr = 11

⇒ 22/7 × r = 11

⇒ r = 3.5

Area of the circle = πr2

⇒ 22/7 × 7/2 × 7/2

⇒ 154/4

⇒ Area of the quadrant = 154/4 × 1/4

⇒ 154/16

⇒ 9.625

⇒ Area of the quadrant = 9.625 cm2

∴ Area of the quadrant is 9.625 cm2
