She needs to answer 16 questions to get -80. (80÷5=16) but since she needs a smaller score than that to win the game, she then will have to answer more than 16 questions correctly. at least 17 to get less that -80. Hopefully I am understanding the question right.

Answer:
The circumference of the circle is 6 cm (approximately).
Step-by-step explanation:
Given:
Area of the circle = 1/4π²
Now, to get the circumference of the circle we need the radius.
So, finding the radius by putting the formula of area:
Area = 
 =
 =  
 
dividing π by both sides:


using square root on both the sides:

So, the radius is 
Now, putting the formula of circumference:

                               =
                               =
putting the value of π =3.14
                               =
                               =
                               =
Circumference = 5.56 cm
Therefore, the circumference of the circle is 6 cm (approximately).
