Question

3. If the perimeter and area of a circle are
numerically equal, then the radius of the circle
is:
2 units
i units
4 units
7 units​

Answer 1

Answer:

Heya user !!!

Here's the answer you are looking for

The perimeter of a circle is 2πr where r is the radius of the circle.

And it's area is πr²

If area = perimeter

Then,

2πr = πr²

2 = πr² / πr = r

Therefore, if r is 2units then the area and perimeter of the circle would be numerically equal.
