Area of a Circle Formula and Examples ChiliMath
WebFinding the Area: Let a = area of the circle. a = πr². If you know the diameter and not the radius, simply divide the diameter by 2 to get the radius and still use the formula above. Again, the formula can be used to solve for the radius, if you know the area. Simply divide a by π to get r² and take the square root of. the result. WebTherefore, the circumference circle equation is C = 2 πr. Example 1: If the radius of a circle is 7 units, then the circumference of the circle will be. 2 × π × 7 = 2 × 3.14159 × 7. = 43.98 units. Example 2: Suppose that the diameter of the circle is 12 feet. Then, we can use the formula πd to calculate the circumference. WebHow to Calculate the Area The area of a circle is: π ( Pi) times the Radius squared: A = π r2 or, when you know the Diameter: A = (π/4) × D2 or, when you know the Circumference: A = C2 / 4π Example: What is the area of … barjak meaning
