What is the circumference of a 2 radius circle?
To calculate the circumference, you need the radius of the circle: Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That’s it; you found the circumference of the circle.
What is a 2 inch radius?
Measure in from the two edges the amount of the radius. For example, if you want a 2-inch radius corner, measure in two inches from the horizontal edge and make a mark then measure in two inches from the vertical edge and make a mark.
