Answer: 2 A=pi x radius squares so 12.56/3.14159 is the radius squared, Now to find the radius take the square root of that. So we have r squared is 3.9997 or very close to 4 so the radius is very close to 2. We can say it is two in this case we say it is two since we are only dealing with hundreds and 3.9997 rounds to 4
