Question: How to improve the accuracy of circumference?
Answer: The only thing I can think of here is to use a very good approximation of pi.
The circumference of a circle is the diameter (or twice the radius) times pi.
Typically, pi is about 3.14. Some use 22/7, some just use 3, which makes no sense to me.
Your best bet is to use the pi button on your scientific calculator, or use several decimal places.
If I don't have a pi button, I might use 3.14159265. I hope this helps!
