So the formula you have to do is A= (pie)(radius)(squared)
divide 6.7 by 2 to find the radius which is 3.35
now do 3.35 * 3.35 ( we are squaring it) which = 11.225
now 11.225 times PIE is 35.264377537
so the answer is 35.264377537
hope that helped!
Answer:
d. 8°
Step-by-step explanation:
It appears as though you intend ∠ECF and ∠ACB to be vertical angles, hence the same measure, 47°. The angle of interest, ∠BCD, is added to that to make ∠ACD, which is 55°. The added angle must be 55° -47° = 8°.

Answer:
i think it is 20 percent
Step-by-step explanation:
A isnt correct because radius goes from center of circle to any point on circle. Chord on the other hand connects 2 points on circle...
B is also false. Secant goes through circle while tangent only touches it in one point.
C is correct. Chord connects as said before 2 points on circle and in some cases it can connect 2 points in such way that it goes through center which is diameter.
D is not correct because chord doesnt have to pass trought center of circle in order to connect any 2 points on circle.
