What is the diameter of C?

22 cm

3.25 cm

6.5 cm

13 cm

13

Step-by-step explanation:

radius is half of the diameter so is the radius is 6.5cm then the diameter is 13  problem solved

13 cm

Step-by-step explanation:

Radius is half a circle & if

Radius times two that would equals diameter

6.5(2) = 13

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
