Answer:

  • C.) 11.8 inches

===========================

Given

  • A circle with diameter d = 18 in,
  • Central angle θ = 75°.

To find

  • The length of the given arc

Solution

Use arc length formula:

  • s = Ï€dθ/360

Substitute the values and calculate:

  • s = 3.14 * 18 in * 75°/360° = 11.8 in (rounded)

The matching answer choice is C.
