Given a circle with a radius of 7, which equation expresses π as the ratio of the circumference of a circle to its diameter?

A) C/7= π
B) C/14= π
C) 7/C= π
D) 14/C= π

the correct option is B

Step-by-step explanation:C= 2πr or πD and since r=7 then D= 14 (7+7) so from the equation C=πD , making π the subject of formulary π=C/D and D=14. Therefore π=C/14 (B)

answer: a and b

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
