1 lip 2024 · Use the formulas to calculate the circumference and area: c = 2πr and A = πr². The circumference should equal c = 2π × 8 cm = 50.265 cm. The area should equal A = π × (8 cm)² = 201.06 cm². To check your results, input the 8 cm radius in the calculator. The results should also be 50.265 cm and 201.06 cm².
2 dni temu · To calculate the circumference of a circle with a radius of 1 meter, simply follow these steps: Multiply the radius by 2 to get the diameter of 2 meters. Multiply the result by π, or 3.14 for an estimation.

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.
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.
Circumference formula: C = π × d (or C = 2 × π × r) Area formula: A = π × r2. Let's break down these formulas and understand what each symbol represents: C stands for circumference, which is the distance around the circle. A stands for area, which is the space covered by the circle.
