A cylindrical vent 8 in in diameter must be cut at an angle to fit on a gable roof with a 3 over 4 pitch. This means that for the vent itself the ratio of rise to run will be 3 : 4. Find the height x of the cut that must be made on the cylinder to make it fit the slope of the roof (See the figure.)The height × of the cut that must be made on the cylinder to make it fit the slope of the roof is ___ in.(Round to the nearest whole number as needed.)
