A line extends up to point F to form triangle CFD. From point E, a line extends diagonally down to the left to point A. Another line extends from point A diagonally down to the right to point B."/>
1.which of the following is a radius of the circle
2.which of the following is a diameter of the circle
3.which of the following is a chord, but not a diameter, of the circle
4.what is the correct way to name a semicircle of the circle
5.what arc is less than a semicircle
6.if DE=6 cm, what deos CE equal
7.if CF=10 in, what deos ED equal
8.which angle is a central angle of the circle
use the circle to answer the questions accept number 8
#1. No, DE is the diameter
#2. ok. So why did you give that same answer to #1?
For the rest, I am assuming that F,A,B are all points on the circle.
#3. Huh? See #2
#5. No. See #2. I think EBA, but it's hard to say, not having access to the picture.
#6. Huh? See #1, #2
#7. AGAIN? If F is directly above C, then CF is a radius. So, DE (remember DE?) is a diameter, so twice as long
#8. No. The vertex of a central angle is (duh!) the CENTER of the circle: C
