Taking the same numbers

Bore 4 inch

Stroke 4 inch

pie is constant 3.142

3.142x (4x4)radius x 4(stroke) = 201.088ci

But in the example you gave the result is 50.27ci for every cylender

What is the correct answer?

Thank you

Bore = 4 inch diameter, divide that by 2 for radius.... however the correct answer is still 100.53 if you are calculating volume :)
