# 10.The circumference of a circle is 22 cm. Calculate the area of its quadrant (in cm2).

PCM sream in 11 , Preparing for JEE

Let the radius of the circle is =r cm Circumference of the circle =22 cm ⇒2πr=22 2×227×r=22 r=72 cm Area of the quadrant =πr24 =227×14×72×72 =778 cm2
Let the radius of the circle is =r cm

Circumference of the circle =22 cm

2πr=22

2×227×r=22

r=72 cm

=227×14×72×72

=778 cm2

To find the area of a quadrant of a circle, we need to first find the radius of the circle using the given circumference, and then use the formula for the area of a quadrant.
