circumference of circle=2pi.r
22cm=2 x 22/7 x r
r =7/2cm
now
area of circle=pi.r^2=22/7 x 7/2 x 7/2
=77/2=38.5 cm^2
22cm=2 x 22/7 x r
r =7/2cm
now
area of circle=pi.r^2=22/7 x 7/2 x 7/2
=77/2=38.5 cm^2

Given,
Circumference = 22cm
Let the radius be = r
Then,
2πr = 2 × 22/7 × r = 22
r = 7/2cm
Area of circle = πr²
= 22/7 × 7/2 × 7/2 cm²
= 38.5 cm²
Circumference = 22cm
Let the radius be = r
Then,
2πr = 2 × 22/7 × r = 22
r = 7/2cm
Area of circle = πr²
= 22/7 × 7/2 × 7/2 cm²
= 38.5 cm²
