The length of any chord passing through the center. Step 3: Finally, the area of a circle for the given radius will be displayed in the output field. Simply input any two values into the appropriate boxes and watch it conducting all calculations for you. You can also use the arc length calculator to find the central angle or the circle's radius. Step 2: Now click the button Calculate to get the area. Calculate the area of a sector: A r / 2 15 /4 / 2 88.36 cm. The equations will be given below so you can see how the. The procedure to use the area of a circle calculator is as follows: Step 1: Enter the radius in the respective input field. Points A and B define the circle and can be changed numerically or. If you wish to calculate the properties of a three-dimensional solid, such as a sphere, cylinder or cone, it's best to use our volume calculator. For those having difficulty using formulas manually to find the area, circumference, radius and diameter of a circle, this circle calculator is just for you. Circle calculator with segment and sector calculation. Use our circumference calculator to find the radius when you only have the circumference or area of a circle. For angles in circles formed from tangents, secants, radii and chords click here. Radius (R) Diameter (D) Circumference (C) Area (A) While a circle, symbolically, represents many different things to many different groups of people including concepts such as eternity, timelessness, and totality, a circle by definition is a simple closed shape. Chord and Arc Calculator Click here for the formulas used in this calculator. ![]() Diameter - The distance across the circle. The circle calculator finds the area, radius, diameter and circumference of a circle labeled as a, r, d and c respectively. Please provide any value below to calculate the remaining values of a circle. Radius - The radius is the distance from the center to any point on the circle. All points on the circle are equidistant (same distance) from the center point. The distance across a circle through the center is called the diameter.Ī circle is a round plane figure whose boundary or the circumference consists of points equidistant from a fixed center.Ĭenter - A point inside the circle. The radius of a circle is the distance from the center of a circle to any point on the circle. This circle equation calculator displays a standard form equation of a circle, a parametric form equation of a circle, and a general form equation of a. ![]() The solution can be shared.Area of Sector = πr² (θ/360) = ½ *arc * (angle in degree)Ī Circle is a set of points that is formed in a closed loop, every point on which is a fixed distance from a center point. All calculations are saved in the history. Another relevant aspect of circles is their circumference.
