Answer:

  • See below

Explanation:

The circle has a circumference:

  • C = 2πr

This the is arc of full length θ = 360°

Each degree of arc length is:

  • s = 2πr*θ / 360 = πrθ / 180

We have:

  • r = 6 in and θ = 25°

The arc length is:

  • s = π*6*25/180 = (5/6)π inches terms of π

The same arc is:

  • s = (5/6)*3.14 = 2.62 inches (rounded)
