Question

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

Answer 1

2pier = pie r.r

2r - r.r = 0

r(2-r) =0

r = 0,2

as r cannot be 0

so it's 2

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.
