Eugene knows the circumference of a circle is 125.6 meters. does he have enough information to find the area?

The answer is “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.”

First change each value into improper fractions, which is 31/2 and 29/8. To divide fractions, keep the first one the same, change to multiplication, and flip the 29/8. So, the equation is now 31/2 * 8/29. Cross cancel the 2 & 8, making the equation 31/1 * 4/29. Multiply 31 by 4 to get the numerator, 124. Then divide 124 by 29 to get the final answer, ~4.27...
