I need to make a circle by only knowing the circumference has to be only of inches, for example I need a circle that has a circumference of exactly 200 inches, how might I figure this out?

Thecircumference of a circle is the edge or rim of a circle itself. It is the equivalent of 'perimeter' for a circle. In other words, if you took a circle and unrolled it, you would have its circumference. You can use either of the formulas below to find the circumference . One formula use the radius of a circle; the other formula uses the diameter.
Formula using Diameter Circumference=π⋅diamete Formula using Radius Circumference=2π⋅radius
These two formulas are just two different ways of finding the same thing (circumference) because the diameter of a circle =2• radius. So you can use whichever formula is more convenient. If you know a circle's radius, use the first version of the formula; if you know the diameter, use the second. Example: Circumference=2π⋅radius 200 = 2 * 3.14 * radius radius = 200/6.28 = 31.84 inches
The Radius is the distance from the center to the edge. So now, a circle is easy to make: Draw a curve that is "radius" away from a central point. And so: All points are the same distance from the center.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
