Consider a conduit that runs between two boxes. The distance between the boxes $($BD$)$ is $91\mathrm{.}4$ inches. A single $10$ offset will be bent in the conduit with a rise $($R$)$ of $3\mathrm{.}9$ inches. Utilize a shrink constant of $0\mathrm{.}087$ to determine the overall conduit $($OAC$)$ length required to complete this run. $($Round your FINAL answer to two decimal places.$)$
