Question

Find the measure of the central angle that you would draw to represent 47% in a circle graph. Round your answer to the nearest degree.

Answer 1

Well I mean the central angle would be from the center, and there are 360 degrees in a circle. If 47% of it is taken up by the section mentioned in the question, we could just do this:
.47*360=169.2, and then rounding to the nearest degree would get you 169 degrees. I think it's how to do it. I could be wrong. I wasn't exactly a fan of geometry when I took it.

Answer 2

@halorazer well that was easy lol thank you i have never heard any question like that.

Answer 3

47% means 47% of area. sector area = (central angle/360)*area
So (sector area/area)*100 = (central angle/360)*100
47 = (central angle/360)*100
Now solve for central angle.

Answer 4

It wasn't given area, sir. No measurements were given aside from the 47% part.

Answer 5

Do tell how we are supposed to find area.

Answer 6

Plus, it's referring to a graph, not an actual object. How can you measure the area of somethign that isn't even real? O.o

Answer 7

Yes it's a graph. You can take any character of circle sector which depends on the central angle. For e.g arc length. But usually, it is taken as area.
