Question 6 of 28 • FL-1205040-M/J Grade 7 Mathematics B -GF
Eugene knows the circumference of a circle is 125.6 meters. Does he have enough information to find the area?
Answer
A
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.
B
Yes, because the area will just be twice the circumference so all he has to do is multiply by 2.
C
No, because the circumference equals and there is no in 125.6.
D
No, because the circumference equals so he could only find the diameter. He needs the radius for the area formula.
