An 8-cylinder engine has a bore of 4.5 inches and a stroke of 4.5 inches. what’s the total piston displacement? a. 71.53 b. 472 c. 72 d. 572

1.) To find the piston displacement, you have to find the volume of cylinder. The formula for volume is V = pi*r^2*h, where V = volume, r = radius, h = height
2.) V = pi*r^2h
         = 3.14*2.25^2*4.5 (bore = diameter; hence r = diameter/2) (height = stroke)
         = 3.14*5.06*4.5
         = 71.4978 or 71.50
3.) Since the engine has 8 cylinders, multiply the piston displacement by 8
        = 71.50*8
        = 572
Therefore, the total piston displacement of an 8-cylinder engine is D. 572
