6 dni temu · There are three circle radius formulas, depending on what number you know: The radius of a circle from the area: if you know the area A, the radius is r = √(A / π). The radius of a circle from circumference: if you know the circumference c, the radius is r = c / (2 × π).
3 dni temu · If you know the radius or diameter of the circle, the area of the circle formula is: a = πr² = π × (d / 2)². If radius and diameter are unknown, you can calculate it from the circumference: a = c² / 4π. If you are interested in calculations of some fraction of a circle, check:
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).
Our Circle Calculator helps you find all essential characteristics of a circle, including radius, circumference, diameter, and area. Tip: Press. to embed for free. Calculate. Understanding the geometry of a circle is crucial in various fields, from engineering to everyday life.
This calculator computes the values of typical circle parameters such as radius, diameter, circumference, and area, using various common units of measurement.
Circle Calculator. With our Circle Calculator, you can determine the area, circumference, radius, and diameter of a circle by entering just one known value. The calculator will automatically calculate the other values. Formulas. This calculator uses the following formulas: Radius = Diameter / 2. Circumference of a circle = 2 × π × Radius.
