Question

If the circumference and the area of a circle are numerically equal then the diameter is

Answer 1

Let the radius of the circle be r units.
Perimeter of the circle = 2πr units
Area of the circle = πr2 sq units
Numerical value of area of the circle = Numerical value of perimeter of circle
So, πr2 = 2πr
⇒ r = 2

Answer 2

Answer:

4units

Step-by-step explanation:

let diameter be r.

so , area of circle = 2πr

= 2πr²

= 2 x 2 π

= 4 units
