+53 The engine displacement of an automobile is the volume through which the piston moves from high to low position. If an engine has n cylinders, the displacement is D = pi • (bore/2)^2 • stroke • n, where the bore is the diameter of the cylinder and stroke is the length of the piston's travel.
1. If bore = k/2 and stroke = h, simplify the expression, D, in terms of k and h for 8 cylinders.
