My usage is hence:
Take your ball, the obvious circumference would be it's widest point when held up, this could be the equator or from pole to pole, or any other point that runs straight through the centre of the ball. In the case of planet earth, this is defined as 40075.02km equatorially...
Thanks for that. I figured that I had just described my aim in a poor manner and have just drawn out a cross-section diagram in paintshop to graphically show what I mean to achieve.
In doing so I have realized that I have made a fundamental and stupid error in thinking that 45 degrees north...
Okay, this one is probably going to get laughed out of town, but it's annoying me so I shall ask it anyway.
1. Take any number of 2 digits or greater, reverse it (i.e. 12 becomes 21 or 4765 becomes 5674).
2. Take the 'reversed' number away from the original number.
3. Why is the answer to...
Okay, I'm not following this entirely. If we have two of the sides of a right-angled triangle then why can the other not be worked out using pythagoras' theorum? Going into real basic maths here, but I was always taught that A2+B2=C2, so surely if you have A and C then C2-A2=B2?
Then it'd just...
Hi all,
Hope you can help. How can I get the circumference of a specific point on a ball, more to the point in this example, the ball is in question is planet earth. Using the polar circumerence I have got the polar diameter and radius (r) (that's the easy bit). Now, what I figured is that...
