Download Solution PDFGiven:
The numerical value of the circumference and the area of a given circle are equal.
Formula used:
Diameter = 2r, Where, r = Radius
Circumference of circle = 2πr
Area of circle = πr2
Calculations:
When the circumference of the circle = area of the circle,
⇒ 2πr = πr2
⇒ r = 2 (π and radius being common gets cancelled out)
Required diameter = 2 × 2 = 4 units
∴ The answer is 4 units
