The volume of a cylinder is given by the formula V=πr²h, where r is the radius and h is the height (or in this case, the length of the pipe).

Step 1: Convert the diameter to radius. The radius is half of the diameter, so r = 3ft / 2 = 1.5ft.

Step 2: Substitute the values into the formula. V = 3.14 * (1.5ft)² * 12ft.

Step 3: Calculate the volume. V = 3.14 * 2.25ft² * 12ft = 84.78ft³.

Step 4: Round to the nearest whole number. V ≈ 85ft³.

So, the volume of the pipe is approximately 85 cubic feet.
