How to Calculate the Area of a Circle You can find the area of a circle using acalculator, or you can use the circle area formula: A = πr² The areaAis equal to pi times the radiusrsquared. How to Find the Circumference
Calculate the circumference of a circle when it's radius or diameter or area is given using this free circumference calculator tool
How to Find Area of a Sector A sector is a pie-shaped piece of a circle consisting of an arc connecting a radius on either side. Just like a pie, a circle can be subdivided into various sectors. Thearea of a sectoris equal to the central angle divided by 360, times π times the ...

To find the area of a circle, you take pi times the radius squared, or A = pi r^2. Using this formula, you can find the area of a circle if you know the radius -- or the diameter -- by plugging in your values and solving for A. Pi is approximated as 3.
assume that the radius of the circle is 1. Then, find the coordinates of the point(x, y) on the unit circle, and find the exact value of each trigonometric ratio. When necessary, leaveyour answer in simplest radical form and as a fraction. (Do not use a calculator!)7n/6(y)Tan(7...
or 3.14. (C = 2πr) In order to find the area of a circle, on the other hand, students must remember that the area is based on Pi multiplied by the radius squared, which is written A = πr2. Use both of these equations to solve the questions on the following eight worksheets. ...
