Answer 1

Heya user
Here is your answer !!

__________

Let the radius of the circle be r .

There fore ,
Perimeter of the circle = 2( pi )r
Area of the circle = ( pi )r^2

There fore ,
Acc. to the question ,

2( pi )r = ( pi )r^2
=> 2r = r^2
=> r = 2 . ( Answer ) .

Hope it helps !!

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.
