Find the area of a quadrant of a circle whose circumference is 44 cm.
Given:
Circumference of circle = 44 cm
Let the radius of the circle be ‘r’ cm
∵ Circumference of circle = 2πr
∴ 44 = 2πr
= × r
r = 22 × = 7 cm
Now, Area of quadrant = × πr2
= × × 7 × 7
= = = 38.5 cm2
Hence, the area of the quadrant is 38.5 cm2.
