Circumference in math terms
WebMar 24, 2024 · A circle is the set of points in a plane that are equidistant from a given point O. The distance r from the center is called the radius, and the point O is called the center. Twice the radius is known as the diameter d=2r. The angle a circle subtends from its center is a full angle, equal to 360 degrees or 2pi radians. A circle has the maximum possible … WebSep 29, 2024 · You may need to use the distributive property to simplify the final answer. For example: Calculate the circumference of a circle with a radius of (x = 1). C = 2πr = 2π (x+1) = 2πx + 2π1 = 2πx +2π = 6.28x + 6.28. If you are given the value of “x” later in the problem, you can plug it in and get a whole number answer.
