Question

if the perimeter and area of a circle are numerically equal, then find the radius of the circle?​

Answer 1

perimeter of circle = area of circle

2πr. =. πr²

r. = 2

hope this answer help you.....

Answer 2

The radius of circle(r) is equal to 2 units.

Step-by-step explanation:

Let r be the radius of circle.

To find, the radius of circle(r) = ?

We know that,

The perimeter  of circle = $2\pi r$

Also,

The area  of circle = $\pi r^2$

According to question,

The perimeter  of circle = The perimeter  of circle

∴ $2\pi r$ = $\pi r^2$

⇒ 2 = r

⇒ r = 2 units

Thus, the radius of circle(r) is equal to 2 units.
