A much simpler way to find the "area of the circular end" that is the area of a cross section of a tube etc. Formula = o/d minus the wall thickness of the tube x pi x wall thickness. (o/d is the outside dia.) e.g. a tube 10 cm outside diameter and 3 cm wall thickness. ( your example ) so 10 minus 3 x pi x 3 = 66 cm Answer in 3 simple calculations. What do you think of this?
