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:
6 dni temu · Input the radius in the circle area formula: A = π × (3 cm)² = 28.2743 cm². Also, input the radius in the circumference formula: c = 2π × (3 cm) = 18.8496 cm. Check your results with the circle formula calculator. The results should also be 28.2743 cm² and 18.8496 cm for area and circumference.
6 dni temu · These are the formulas to calculate the circumference and area of a circle: c = 2πr A = πr² = πd²/4. where: c stands for circumference; r for radius; and; d for the diameter of the circle. π is a constant approximately equal to 3.14159265359 and, among other things, represents the circumference-to-diameter ratio of any circle.
Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd
This calculator computes the values of typical circle parameters such as radius, diameter, circumference, and area, using various common units of measurement.
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. Area of a circle = π ...
