I’m having troubles with this one.

239 degrees.

Arc is circumference so length = r * 4.17133691221

Step-by-step explanation:

We eliminate RSQ in degrees = 90 + 31 = 121

So that;

RPQ = 360 -121 = 239 degrees

2pi radius (239/360) = r6.28318530718 (0.66388888888)

= r * 4.17133691221

could you reply to this with the question so i can ?

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.
