A:You have the formula correct at 0.375 in.However, I believe you misinterpreted the meaning and how it relates to your bend allowance chart. The calculated 0.375-in. radius is the minimum producible inside radius for this material and not the recommended inside radius that you see on the bend allowance chart.
