Answer:
The area of a quadrant of a circle whose circumference is 22 cm is 77/8 cm2.
Step-by-step explanation:
Let the radius of the circle be 'r'
Thus, the circumference C = 2πr
Therefore, r = C/2π
A quadrant of a circle means one of the four equal parts.
Therefore, the area of a quadrant = 1/4 × Area of a circle = 1/4 × πr2
Circumference (C) = 22 cm
Therefore, radius (r) = C/2π
= 22/(2 × 22/7)
= (22 × 7)/(2 × 22)
= 7/2 cm
Therefore, the area of a quadrant = 1/4 × πr2
= 1/4 × 22/7 × 7/2 × 7/2
= 77/8 cm2
