Answer 2

It is given that the area of the circle is 4π.

The theorem for area of a circle is πr², or pi x radius². Knowing this, we can work backwards to find our radius.

Knowing that the answer is squared, we can find the square root of 4π to get our next value.

$\sqrt{4pi$ = ~3.54490770181

Knowing this, we can divide by pi to get the value of our radius, following inverse operations.

~3.54490770181 / π = ~1.1283791671

Therefore, ~1.1283791671 is the radius of the circle.
