Answer:
4.708 feet
Step-by-step explanation:
Given that: The sector area A=28.25 ft2
The radius r = 12 feet
....attached work below
Now the length of steel (Arc length ) = 2πr/2π × θ
The length of steel (Arc length ) = r × θ
The length of steel (Arc length ) = 12 × 0.39236
The length of steel (Arc length ) = 4.708 feet
