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
