6 dni temu · The radius of a circle calculator returns the length of a circle's radius based on the input data: the circumference, area, or diameter.
6 lut 2024 · Calculate the area, circumference, radius and diameter of circles. Find A, C, r and d of a circle. Given any 1 known variable of a circle, calculate the other 3 unknowns. Circle formulas and geometric shape of a circle.
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.
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).
Please enter the circumference to calculate the radius, the diameter and the area of the circle. The help texts of the calculated circle properties are updated and each contains a concrete derivation of the current calculation, i.e. from the circumference to the radius, to the diameter or to the circle area.
To calculate the area of your circle, you can multiply the square of a radius by pi and get the area of your circle. Area = radius² × π. Example: You want to know what the area of a circle with a radius of 1.5 meter is, the formula would look like this: 1.5² × π = 7.07 m2.
