1. Divide by Pi Begin by dividing your area by π, usually approximated as 3.14: 50.24ft2÷3.14=16ft2 You aren't quite done yet, but you're close. The result of this step represents r2or the circle's radius squared. 2. Take the Square Root Calculate the square root of the ...
The areaAis equal to pi times the radiusrsquared. How to Find the Circumference You can find the circumference of a circle using acalculator, or you can use the circumference formula: C = 2πr The circumferenceCis equal to 2 times pi times the radiusr. ...
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 3.14. Whole Numbers Whole...
If the circumference of a circle is 26 \pi cm, then what is the radius of the circle? What is the circumference of a circle whose area equals 20 times 3.14 cm squared in centimeters? What is the perimeter of a square which has the same area as a circle with a circumferen...
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. ...
