n circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.

Circle O is shown. Line segments L O , M O, and N O are radii. The length of L O is 6 centimeters. Angle M O N is 75 degrees. The measure of arc L M is 6.3 centimeters.

Rounded to the nearest tenth of a centimeter, what is the length of arc LMN?

7.9 cm
10.2 cm
12.6 cm
14.2 cm

Arc MN = r * θ (θ in radians). For θ = 75° = 75π/180 = 5π/12 rad,

MN = 6 * (5π/12) ≈ 7.854 cm.

Total arc LMN = LM + MN = 6.3 + 7.854 ≈ 14.154 cm ≈ 14.2 cm.

Answer: 14.2 cm.
