What is the 'center to center' measurement for a 45 degree, 10 inch offset when multiplied by 1.414?

Explanation:
When a pipe is offset at 45 degrees, the center-to-center length is the diagonal distance corresponding to the horizontal and vertical offsets. That diagonal length is the offset multiplied by sqrt(2). So a 10-inch offset becomes 10 × 1.414 ≈ 14.14 inches. In plumbing practice, we round to the nearest common fraction; 14 1/8 inches (14.125) is the closest to 14.14, which is why that option is chosen. The other fractions are farther away: 14 inches is short by about 0.14 inches, 14 3/16 is about 0.045 inches over, and 14 1/4 is about 0.108 inches over.
