If the measurement of a central angle is [tex]5x[/tex], find the length of its intercepted arc in a circle with a radius of 15 inches.

A. 33.4 inches
B. 35.6 inches
C. 37.5 inches
D. 39.3 inches

Answer :

The length of the intercepted arc is approximately 39.3 inches. Therefore, the correct answer is option D.

To find the length of the intercepted arc when the central angle is [tex]\frac{5\pi}{6}[/tex] radians in a circle with a radius of 15 inches, we use the formula for arc length :

  • Arc Length = θ × r
  • θ = [tex]\frac{5\pi}{6}[/tex] radians
  • r = 15 inches
  • Substitute the given values into the formula :

Arc Length = [tex]\frac{5\pi}{6}[/tex] × 15 = [tex]\frac{75\pi}{6}[/tex] = 12.5[tex]\pi[/tex] = 12.5 × 3.14 ≈ 39.3 inches

  • Therefore, the length of the intercepted arc is approximately 39.3 inches.

Complete Question

If the measurement of a central angle is 5pi/6, find the length of its intercepted arc in a circle with a radius of 15 inches

a 33.4 inches

b. 35.6 inches

C. 37.5 inches

d. 39.3 inches

Answer:

d. 39.3 inches

Step-by-step explanation:

We are to find the Arc length of the circle

To solve the above question, the formula is given as:

Arc length = Central angle × radius

From the above Question, we are given:

Central angle = 5pi/6 = 5π/6

Radius = 15 inches

Hence,

Arc length = 5π/6 × 15 inches

Arc length = 235.61944901923448/ 6

Arc length = 39.26990817 inches

Approximately , the Arc length

= 39.3 inches.

Therefore, Option d is the correct answer.
