THE CIRCUMFERENCE OF A CIRCLE IS 22/7 x THE DIAMETER SO ---IF YOU INCREASE THE DIAMETER OF A CIRCLE FROM 2 INCHES TO 3 INCHES,THE INCREASE IN CIRCUMFERENCE IS 3.142 INCHES.
IF THE CIRCLE DIAMETER IS 1 MILE[66360 INCHES]AND IS INCREASED BY 1 INCH,THE RESULT IS THE SAME-3.142!
IF THE EARTH WAS A PERFECT SPHERE DOING THE SAME CALCULATION WITH THE EQUATOR WOULD YIELD THE SAME 3.142 INCHES!!!
LIKE I SAID, IT DONT SEEM RIGHT.
PLEASE WILL SOMEONE PUT ME RIGHT!
I know what you mean. It is counter-intuitive, but it is indeed the fact.
A couple of examples:
Circle with 10 inch diameter has a circumference of 31.42 ins
Circle with 11 inch diameter has a circumference of 34.562 ins and the difference is 1 x 3.142 inches.
Circle with 10,000 ins diameter has a circumference of 31,420 ins
Circle with 10,001 ins diameter has a circumference of 31,423.142 ins and the difference is 1 x 3.142 inches.
Yes, if you put a rope along the ground on the equator all around the earth and another rope 1 metre above the ground all the way round the earth, the second rope would only be around 6 metres longer
If the earth was a cube and you increased it's sides by one inch you would get an extra inch on each side so it's (square) diameter would increase by 4 inches.

For the purpose of this little observation,it doesnt matter if Pi is 22/7 or 3.142******,its obvious I did geometry at school a long long time ago but I cant get my head around" 3.142 inches"!!!

A slight deviation from the OP but I thought you may like it.
