Question

If the perimeter and area of the circle are numerically equal. Then find the radius of the circle.

Answer 1

Step-by-step explanation:

perimeter of circle equal to 2^r.

area of circle equal to πr square.

hence,perimeter of circle=area of square

2πr=πr×r

r=2 unit.

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.
