A6.375 inches
B7.812 inches
C8.185 inches
D8.312 inches
AI Explanation
The correct answer is B) 7.812 inches. To arrive at this answer, we need to calculate the tapered length "X" based on the given dimensions. The overall length of the shaft is 42 inches, and the lengths of the other sections (A, B, C, and D) add up to 34.1875 inches (8 + 8 + 10 + 8.1875). Therefore, the tapered length "X" is the remaining length, which is 42 - 34.1875 = 7.8125 inches, or approximately 7.812 inches. The other answer choices are incorrect because they do not accurately reflect the tapered length "X" based on the given information.
