circumference=22cm
=>2πr=22
r= 22/2×π
=>r=22×7/2×22
=>r= 7/2
area =πr²
=> 22/7×7/2×7/2 by cancelling we will left with
=>77/2=38.5cm²
hope ut helps u

2 pi r=22
pi r=11 --> r= 11/22×7--> r=77×22-->r=7/2
area of circle = pi r square
pi r Sq. = 22/7×7/2×7/2
=11×7/2
= 77/2 -->36.5
pi r=11 --> r= 11/22×7--> r=77×22-->r=7/2

=11×7/2
= 77/2 -->36.5
