If the measurement of a central angle is 5π/6, find the length of its intercepted arc in a circle with a radius of 15 inches.
Artist 52 [7]

Answer: d. 39.3 inches

Step-by-step explanation:

Given the measurement of central angle ( \frac{5\pi}{6} ) and the measure of radius (15 inches), the lenght of the intercepted arc in the circle can be calculated with the formula:

arc\ length=r\theta

Where r represents the radius of the circle and \theta the central angle.

Substituting \theta=\frac{5\pi}{6} and r=15inches into the formula arc\ length=r\theta:

arc\ length=(15inches)(\frac{5\pi}{6})\\arc\ length=39.3inches
