Question

If the perimeter of a circle is equal to its area numerically. What is the measurement of radius?​

Answer 1

Step-by-step explanation:

Given:- perimeter of circle = area of circle

2πr = πr^2

2r = r^2

r = 2

hence, radius = 2 unit

Answer 2

The measurement of radius (r) is 2 units.

Step-by-step explanation:

Let r be the radius of circle.

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

We know that,

The perimeter of a circle = $2\pi r$

Also,

The area of a circle = $\pi r^2$

According to question,

The perimeter of a circle = The area of a circle

∴ $2\pi r$ = $\pi r^2$

⇒ r = 2 units

∴ The measurement of radius (r) = 2 units

Thus, the measurement of radius (r) is 2 units.
