17.If the diameter of a circle is 18 feet, which is closest to the circumference? a. 56.52 feet
b. 9 feet
c . 5.73 feet
d . 28.26 feet

a. 56.52 feet

Step-by-step explanation:

Circumference= pi* diameter

pi*18= 56.54

56.54 is closest to 56.52

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.

the answer is 99.
