50-36-4 se r= 6 and b = 9

75

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.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

unless if u could do my questions, if not i wouldn't want to
