3. From the given figure, solve for the bar X from the reference line (choose the nearest answer)

A piston engine in which the bore and stroke are of equal dimension is referred to as a "square engine". An 8-cylinder square engine has a displacement of 305 in3. What is the bore and stroke? Round to the nearest thousandth of an inch. "bore" is the diameter of a cylinder, and "stroke" is the height of a cylinder (the distance the piston travels in one stroke). You will need the formula for the volume of a cylinder to solve this problem.

You are in an inventory management field these days. You are working for a place which works on 365 working days per year. The annual demand is 901 widgets per year.
