Circle calculator code#
If you know the area of a circle, you can calculate the radius based on the following formula: a c b a 2 + b 2 c 2 a 2 + b 2 c c 2 - b 2 a c 2 - a 2 b a 2 + b 2 c 2 r d A r A C 2. We thank our donors, partners, our extended team, our video cast, and our education advisors for their support in creating Code Studio. The Circle Calculator is used to calculate the area, circumference, diameter or radius of a circle. Lines that intersect the circle in exactly one point. Calculating the Radius of a Circle Using Area. Lines that intersect the circle twice are called secants. We can see this on the graphic below: You can also work out the circumference of a circle if you know its radius. This tells us that the circumference of the circle is three and a bit times as long as the diameter. What interesting lines exists for a circle?įirst of all, there are lines that don't intersect the circle that are called passants. Circumference of circle x Diameter of circle This is typically written as C d. If you know circumference, Area A C² / 4. Area of Circle Formula: If you know radius, Area A r². , in which pi is the circle constant (approximately 3,14).Įnter a few values into the input fields and press „calculate“. The simple and universal formulas to calculate area, circumference and diameter of circle are here. U = 2 multiplied with pi multiplied with r Radius (in units of length): Fill in the radius to find. Circle calculator - circle calculator is used to calculate the radius, circumference, area and diameter of a circle and along with the formula of circle. Using the unit circle calculator is easy and quick. A unit circle or a trigonometry circle is simply a circle with radius 1 unit. And there you go the circumference of a circle with a radius of 1 meter is 6.28 meters. Unit circle calculator is an extremely handy online tool which computes the radians, sine value, cosine value and tangent value if the angle of the unit circle is entered. Multiply the result by, or 3.14 for an estimation. The following formulas are used for circle calculations. Find the area of a circle by using this online Circle Calculator. 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.
This is the total length of the edge around the circle with the specified diameter, if it was straightened out.These are the formulas for calculating circles:Ī circle is a shape with all points at the boundary having the same distance to the centre. This calculator converts the area of a circle into an oval area of the same size.
The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are exactly 180 degrees apart. ø Circle diameter C Circle circumference. The formula used to calculate the circle diameter is: ø C /. This tool will calculate the diameter of a circle from the circumference, and will convert different measurement units for circumference and diameter. The formula used to calculate circle circumference is:Įnter the diameter of a circle. Sphere surface area to diameter calculator User Guide. This tool will calculate the circumference of a circle from the diameter, and will convert different measurement units for diameter and circumference. Sphere diameter to surface area calculator.Sphere volume calculator using diameter Find the three missing circle measurements from one known measurement: area, circumference, diameter, or radius.Circle radius calculator using diameter.Calculate diameter of circle from circumference.
