Minimum fiber bending radius equals 10 times the diameter. If diameter is 0.25 inches, what is the radius?

Explanation:
The key idea is the specified relation between diameter and bend radius: the minimum bend radius is 10 times the diameter. So multiply the diameter by 10 to get the radius. With a diameter of 0.25 inches, 0.25 × 10 = 2.5 inches. Therefore, the minimum fiber bending radius is 2.5 inches. (Note: geometrically, radius would be half the diameter, but the given requirement uses the 10× rule, which is why the result is larger.)
