Answer:

5π or 15.71 inches

Step-by-step explanation:

Length of an arc = [tex]\frac{x}{360}[/tex] × 2πr

Where x is the angle and r is the radius

so  [tex]\frac{90\\}{360}[/tex] × 2 × π × 10

0.25 × 2 × π × 10

Arc length = 5π inches (answer in terms of π)

= 15.71 inches (answer in two decimal places)
