Question

1. Find the length of arc PRQ: Show your work.

Answer 1

The length of arc PRQ is 16.7 in.

Explanation:

Given;

• r = 8 in
• θ = 120°

So,

arc length = 2πr × (θ/360)

arc length = 2(3.14)(8) × (120/360)

arc length = 2(3.14)(8) × (120/360)

arc length = 50.24 × (1/3)

arc length = 16.7 inches

Thus, The length of arc PRQ is 16.7 in.
