Question

Find the area of a quadrant of a circle whose circumference is 44 cm.

Answer 1

Let the radius of the circle be r.

​Now, 

Circumference = 44 

⇒ 2πr = 44

⇒ r = 7 cm

Now,

Area of quadrant`=1/4pi"r"^2 = 1/4xx22/7xx(7)^2 = 38.5  "cm"^2` 

Hence, the area of the quadrant of the circle is 38.5 cm².
