Answer 2

SOLUTION

TO FILL IN THE BLANK

It the length and area of a circle is same, then the radius of the circle is __________ units.

EVALUATION

Let radius of the circle = r unit

∴ Length of the circle = 2πr unit

∴ Area of the circle = πr² sq.unit

So by the given condition

$\sf{\pi {r}^{2} = 2\pi r}$

$\sf{\implies \: r = 2}$

Hence the required radius of the circle

= 2 unit
