So since I'm trying to get a better score with engagement I'm going to walk you threw this step by step:

The first thing we need to do is figure out the original circumference of the pie. Do you know how to do that?

anonymous · Answer

The diameter x pi?

anonymous · Answer

Okay screw it your not even in the room,  3.5 inches is the original radius, so now we are going to take that and 3.5^2 and that will give you the circumference I believe.

anonymous · Answer

diameter is the radius time 2.

anonymous · Answer

radius is exactly half of the diameter.

anonymous · Answer

Ok. Got it.

anonymous · Answer

So do you have the circumference?

anonymous · Answer

Wouldn't it be 38. 465? 
The diameter is 12.25 and I multiplied that by 3.14 for pi.

I study this a week or two ago but I know background knowledge and I dont eel like going back and searching for my notes on this. I remember it being r^2 = c so punch that into the calculator and tell me what you get.

Okay heres the formula for the answer good luck :D 

r^2 = c will give you the whole original pie. 
I know that the answer is not 10$ because that would mean that it is the whole pie and cirlces do not have angles :/ then you need to look at the angle of 240 and I would estimate that the answer is 6$ because around 2 slices are missing :/
