D = 2 √ a/π (use calculator)

The square root of 1 = 1

1 * 1 = 2

Diameter = 2

C = πd (use a calculator)

Circumference = 6.28

C = 2

A = πr ²

Now divided both sides by π

A/π = r ²

Substitute the area of the circle for the variable A

r = √3.14 π

Divide the area by π

r = √ 3.14/3.14

r = √=1

The square root of 1 = 1

Radius = 1
