Question

If the perimeter and the area of a circle are numerically equal, then find the radius of the circle

Answer 1

Perimeter =2 πr

Area = πr^2

2 πr= πr^2
r=2 units

Answer 2

Hey there!

Answer:

$\boxed{\boxed{r=2}}$

Step-by-step explanation:

Perimeter of circle  = 2πr

Area of circle  = πr²

According to the Question,

Perimeter of circle = Area of circle

2πr = πr²

or, 2πr / πr = r

or, 2 = r

or, r = 2

Hence the radius is 2.
