31 sty 2024 · You can find the area of a circle using the radius, the diameter, or the circumference. To find the area using the radius, or the length from the center of the circle to the edge, use the formula area = πr^2, where r is the radius. For example, if the radius of the circle is 6 inches, first you would square 6 and get 36.
Task 1: Given the radius of a circle, find its area. For example, if the radius is 5 inches, then using the first area formula calculate π x 5 2 = 3.14159 x 25 = 78.54 sq in. Task 2: Find the area of a circle given its diameter is 12 cm. Apply the second equation to get π x (12 / 2) 2 = 3.14159 x 36 = 113.1 cm 2 (square centimeters).
Calculator. Enter the radius, diameter, circumference or area of a Circle to find the other three. The calculations are done "live": How 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.
The area of a circle can be found using the following formula: A = πr 2. where A is area, r is radius, and π is the mathematical constant approximately equal to 3.14159. Alternatively, if using the circle's diameter, D, the area is: Or, if using the circle's circumference, C, the area is:
