Eugene knows the circumference of a circle is 125.6 meters. Does he have enough information to find the area?
Yes, because he could divide by 3.14 to find the diameter and then divide that result by 2 to find the radius. Once he has the radius, he can use the formula.
Yes, because the area will just be twice the circumference so all he has to do is multiply by 2.
No, because the circumference equals c=diameter and there is no pi in 125.6.
No, because the circumference equals c=diameter so he could only find the diameter. He needs the radius for the area formula.
