Compression ratio is exclusive to each cylinder, though they will all have the same result if they are the same dimensionally ( and they always are) > Divide the total engine capacity by the number of cylinders, this gives the capacity or swept volume of each cylinder (bore * stroke) > So in a 2.0 (2000 cc) litre 4 cylinder engine, each cylinder has a 2000 / 4 = 500 cc swept volume (bore * stroke) > The combustion chamber is the volume remaining at top dead centre (TDC) > Compression ratio = volume at BDC (swept volume + volume at TDC) / volume at TDC
Volume of cylinder= pie x 72 x 4 = pie.196 = 616 cubic units.(Taking pie= 22/7)
Cylinder height in cm = volume/(pi*radius2)
Volume of the cylinder = pi*22*10 = 125.664 cubic inches rounded to 3 decimal places
The answer is 226.19 units2The formula is AL = 2*Pi*radius*height
