... Now, think about a cylinder, it has a height, and if you look at it from the top, it is a circle. Now take a pair of scissors and slice up the side, It unrolls into a rectangle. one set of sides of the rectangle are the height of the cylinder, and the other sides have a relationship to the diameter of the recently destroyed circle. Back to Ms Hinchleys class, the side in question represents the CIRCUMFERENCE of the circle, which has the formula, circumference= 2(pi)Radius = (pi)Diameter where pi is a very specific value approximately 3.1415. We'll skip the discussion on where the 3.1415 came from, but trust me on this. Well now the cylinders of a rocket, at any scale, in any unit of measure are a mere mathematical calculation away. With MS Word, I can now make the circles and rectangles exactly those dimensions, and,... On Mar 23, 11:00 pm, abbe <[email protected]> wrote: > Hi All, > I'm kind of new to this and need some help.
