Find the length of the arc. Round your answer to the nearest tenth.

Answer:
7.1 in
Step-by-step explanation:
Given:
θ = 45°
Radius (r) = 9 in.
Required:
Length of the arc
Solution:
Arc length = θ/360 × 2πr
Plug in the values
Arc length = 45/360 × 2 × π × 9
Arc length = 7.06858347 = 7.1 in (nearest tenth)
