The area of a circle is the plane region bounded by the circle's circumference. It can be found using the formula A = πr2 where r is the circle's radius. If using the diameter, d, of the circle: If the circumference of the circle, C, is known: See more The circumference, C, of a circle is a measure of the distance around the circle. It can be found using the formula C = 2πr where r is the circle's radius. If using the diameter, d, of the … See more In coordinate geometry, a circle can be expressed using a number of equations based on various constraints. See more WebFinding a Circle's Center. We can use this idea to find a circle's center: draw a right angle from anywhere on the circle's circumference, then draw the diameter where the two legs hit the circle; do that again but for a different diameter; Where the diameters cross is the center!
