Heya user !!!

Here's the answer you are looking for

The perimeter of a circle is 2πr where r is the radius of the circle.
And it's area is πr²

If area = perimeter

Then,

2πr = πr²

2 = πr² / πr = r

Therefore, if r is 2units then the area and perimeter of the circle would be numerically equal.

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.
