I have a circle that measures 42" in diameter. I have to put fabric around that at a 2.5 to 1 fullness. What is the flat piece of fabric I need
What else can I help you with?

How do you work out the circumferance if the diameter is 100mm?
circumference = pi*100mm
What is the diameter if a circle measures a circumferance of 39 inches?

Why does pi multiplied by diameter equal the circumference of a circle?
Well, I asked my math teacher and thi is what she said. Okay. A long time ago there were math mathematicians. They had circles sculpted out of rock and wood and stuff like that. So anyway, these mathematicians, or MAs would study the circles by mesuring them. The MA's would take a tape and measure all the way around a circle. They then would measure across the circle. The would do big circles and small circles. They then noticed that there was a pattern. If the mutiplied the distance across the circle times a number, they would get the circumferance. The number was, 22/7 or 3.14...and pi was born. So of course we know that the decimal isn't perfect and we won't get an exact answer when mutipling by pi. But now at least we don't have to cut a circle out of stone and use a measuring tape to determine it that way. ~Minicooper Out!
What is the circumferance of the moon?
The circumferance of the moon is 6790 miles.
How do you label a circumferance?
SQUARED.
How do you get the radius from the circumference?
The circumferance of a circle is equal to 2 x pi x r, where r is the radius, i.e. approximately 6.2832 than its radius. Divide the circumferance from the figure above to get the radius of a circle in which the circumferance is known.
What is 2 x pi x r?
circumferance
What is the circumferance of 10m dia circle?

How do you change circumferance into diameter?
circumference/pi = diameter

How do you work out the circumferance if the diameter is 100mm?
circumference = pi*100mm
