Our calculator calculates it immediately. It does not matter whether you enter radius or area of circle. radius, diameter, perimeter/circumference, or area) and the other three are instantly computed. Calculate quickly circumference or area of circle. Built-in unit converter makes it a snap to calculate and convert from any length or area units. Able to calculate either the radius, diameter. Circle Calculator allows you to calculate radius, diameter, perimeter, and area given any value. It can also be defined as interspace between the two points along a section of a curve. It is ideal for carrying out quick and accurate value calculations. The arc of a circle is also known as arc length which is defined as the distance along the part of the circumference of any circle or any curve (arc).
#Circle calculator how to
Please follow the steps below on how to use the calculator: Circle calculator - circle calculator is used to calculate the radius, circumference, area and diameter of a circle and along with the formula of circle. Online Arc of a Circle Calculator helps you to calculate the arc length in a few seconds. A Circle area Pi 3.14159 ø Circle diameter Diameter of Circle. The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circumference of the. The formula used to calculate circle area is: A x (ø/2) 2. This calculator calculates for the radius, length, width or chord, height or sagitta, apothem, angle, and area of an arc or circle segment given any two. 'Arc of a Circle Calculator' is an online tool that helps to calculate the arc length for a given central angle and radius. Find the three missing circle measurements from one known measurement: area, circumference, diameter, or radius. This tool will calculate the area of a circle from the diameter, and will convert different measurement units for diameter and area. For angles of 2 (full circle), the area is equal to r: 2. Then, we want to calculate the area of a part of a circle, expressed by the central angle.

The full angle is 2 in radians, or 360 in degrees, the latter of which is the more common angle unit. With the calculator on the left, you can input the radii of three mutually tangent circles and find the radii of the interior and exterior fourth circle.A circle is formed by the set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) in the plane. The area of a circle is calculated as A r.
The gray circles are the three given osculating circles, and the pink circles are the possibilities for the fourth mutually tangent circle. The diagram below shows three different cases of Soddy circles: (1) when the exterior fourth circle circumscribes the three circles, (2) when the exterior Soddy circle does not circumscribe the other three, and (3) when the outer Soddy Circle is a line (a circle of infinite radius).
If three circles are mutually tangent (osculating circles, or "kissing" circles), there is a circle in the interior that is mutually tangent to the three, as well as an exterior circle mutually tangent to the three.įour mutually tangent circles are known as Soddy Circles, after the radiochemist Frederick Soddy who rediscovered Descartes' Theorem for finding the radii of these circles.
