What is the approximate length of arc s on the circle ?
a) 5.23 in
b) 41.87 in
c) 52.36 in
d) 104.67 in

By definition, the arc length is given by:
 s = R * theta
 Where,
 R: radio
 theta: angle
 Substituting the values we have:
 s = 15 * (200 * (pi / 180))
 s = 52.36 in
 
 The approximate length of arc on the circle is:
 C) 52.36 in
