Given that the 3 arcs are congruent, it means they have the same angle.
A circle measures 360 degrees, thus, let us divide it into three parts to get the arc length of the 3 arcs RC, CS, and SM which is in Circle A.
360 degrees / 3 = 120 degrees
Again, the three arcs are congruent so the length of arc RC is 120 degrees, same with arcs CS and SM.
Well...according to my calculator and Apologiabiology's math, i got 4.75, idk if this is correct though
18 yards.
i hope this helps!
What variable are you solving for ?
