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
