Quizplus · Accepted Answer

The formula to find the volume of a cylinder is V = πr^2h, where r is the radius and h is the height. In this case, the radius is half the diameter, which is 4/2 = 2 inches. The height or length of the rod is 14 inches. 
Substituting these values into the formula, we get V = π(2)^2(14) ≈ 180 in^3. So, the correct answer is B, 180 in^3.
