Points B and C lie on a circle with center O and radius r = 5 units. If the length of is 10.91 units, what is m in radians? Use the value = 3.1416, and round your answer to three decimal places.
A.1.667
B.2.314
C.2.182
D.2.921
we know that [the length of a circumference]=2*pi*r for r=5 units so [the length of a circumference]=2*pi*5-----> 31.416 units
if 2pi radians (full circle)-------------> has a length of 31.416 units then X radians-----------------------------> 10.91 units X=10.91*2*pi/31.416---------> =2.182 radians
