Circumference = 4π
2πr = 4π
r = 2 .
Radius = 2 units.
Area of circle = π ( r² ) = π(2²) = 4π square units.
2πr = 4π
r = 2 .
Radius = 2 units.
Area of circle = π ( r² ) = π(2²) = 4π square units.

Hi!
Circumference= 4π
Circumference formula= 2πr
So,
2πr=4π
2r=4
r= 4/2
r= 2 units
Area of a circle= πr^2
= π×2×2
= 4π sqaure units
Hope it helps...!!!
