Question

Find the area of quadrant of circle whose circumference is 33cm?

Answer 1

Step-by-step explanation:

To find the quadrant of a circle we will have to first determine the circumference of the circle which is 2πr.

Here, the circumference being 44cm, 2πr=44.

Therefore, radius of circle = r=44/2π =44*7/2*22= 7cm. (π=22/7)

Now, Area of circle = πr^2 = 22*(7^2)/7 = 154.06 cm².

The area of the quadrant of a circle whose circumference in 44 cm is = 154.06 cm².
