Question options:
9.77 cm

6.22 cm
+36916 IF RAM is a diameter, then ANGLE RAC is 180 degrees - 40 = 120 degrees.
The TOTAL circumference of the 360 degree circle is pi x d = pi x 2 r = pi x 2 x 8
The fraction of this total circumference is 140 degrees oout of 360 degrees or 140/360 of the entire circumference
Thi.s equals (140/360 ) * pi * 2 * 8 = 19.55 cm
