let the radius be r units
perimetre of the circle=2πr units
area of the circle= πr²
numerical value of area of the circle=numerical value of perimeter of circle
⇒2πr=πr²
∴radius=2
perimetre of the circle=2πr units
area of the circle= πr²
numerical value of area of the circle=numerical value of perimeter of circle
⇒2πr=πr²
∴radius=2

2pi*r=pi*r^2
r=(2pi*r)/(pi*r)
r=2
r=(2pi*r)/(pi*r)
r=2
