• A. 1 unit
• B. 2 units
• C. 3 units
• D. 4 units

Answer 1

The correct option is B 2 units

Let the radius of circle is r

Then area of circle =$\pi r^2$

And circumference of circle=$2\pi r$

As per question area of circle and circumference of circle is equal in units

$\therefore \pi r^2=2\pi r\Rightarrow r=2$ units
