We are not to be held responsible for any resulting damages from proper or improper use of the service. You can enter the diameter and then compute radius and circumference in mils, inches, feet, yards, miles, millimeters, centimeters, meters and kilometers.. Compute the area using these units: square mils, square inches, square feet, square yards, square miles, acres, hectares, square millimeters, square centimeters, square meters, and square kilometers. It is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. It is one of the easiest clothing to stitch.
This free area calculator determines the area of a number of common shapes using both metric units and US customary units of length, including rectangle, triangle, trapezoid, circle, sector, ellipse, and parallelogram. Learn more about pi, or explore hundreds of other calculators addressing finance, math, fitness, health, and more. Infact, all the numbers are …
Calculation is easy once you have measured the circle's radius or diameter, or if you know it from plans and schematics: just plug the numbers into the formulas above use our area of a circle calculator above.
Then enter the value of the Waist and choose the unit of measurement from the drop-down menu. Please provide any value below to calculate the remaining values of a circle.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.

How to Measure Circles.
This distance is called the radius of the circle, or r for short.
Circle Formulas in terms of Pi π, radius r, and diameter d Radius and Diameter: r = d/2 d = 2r Area of a circle: A = π r 2 = π d 2 /4 Circumference of a circle: C = 2 π r = π d. Circle Calculations: This concept can be of significance in geometry, to find the perimeter, area and volume of solids. You can also use the arc length calculator to find the central angle or the radius of the circle. Use this calculator to easily calculate the area of a circle, given its radius in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc. Plus, unlike other online circle calculators, this calculator will show its work and give a detailed, step-by-step explanation of … This free circle calculator computes the values of typical circle parameters such as radius, diameter, circumference, and area, using various common units of measurement. Area of a circle formula The formula for the area of a circle is π x radius2, but the diameter of the circle is d = 2 x r 2, so another way to write it is π x (diameter / 2)2.
