What is the total piston displacement (cubic inches) on an 8-cylinder engine with a 3 ½ inch diameter and a 4 3/8 inch stroke? Round your answer to the nearest whole number. Use the formula V_d = 0.785 x d² x s x n
Where:
d is the bore or diameter of the piston
v is the volume of the cylinders
s is the stroke or piston travel length
n is the number of pistons

Solution
V_d = 0.785 x d² x s x n
V_d = (0.785)(3.5²)(4.375)(8)
V_d = (0.785)(12.25)(4.375)(8)
V_d = 336.56875
V_d = 337 cubic centimeters
