WebJul 3, 2024 · The area of a circle is the total area that is bounded by the circumference. Think of the area of the circle as if you draw the circumference and fill in the area within the circle with paint or crayons. The formulas for the area of a circle are: A = π * r^2. In this formula, "A" stands for the area, "r" represents the radius, π is pi, or 3.14. WebFORMULAS FOR THE EQUATION OF A CIRCLE Some of the formulas that produce the graph of a circle in polar coordinates are given by r = acosθ and r = asinθ, wherea a is the diameter of the circle or the distance from the pole to the farthest point on the circumference. The radius is a 2, or one-half the diameter. 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!
