A.
E
 
 B.
r

linn99123 · Answer

C. FE(has a line on top of FE)

D. AC(has a line on top of AC)

linn99123 · Answer

I picked D

johnweldon1993 · Answer

Not quite...D) AC

AC spans the full circle...so it is classified as a DIAMETER  ...we want a radius...which is half the diameter

Does that make sense @linn99123 ?

linn99123 · Answer

A little yes :)

linn99123 · Answer

im not the smartest when it comes to circles and radius and fractions lol..

johnweldon1993 · Answer

Alright...so D would be incorrect...since that is A to C ....that is fully across the circle (diameter) 

We want one of those that only goes HALFway across :)

johnweldon1993 · Answer

Lol don't worry about it neither was I at a time :)

linn99123 · Answer

so is FE the same as AC?

johnweldon1993 · Answer

Not at all...F would be at the middle of the circle...and E is at the edge...so FE would actually be our answer...

Does that make sense?
