A chord is a straight line that connects two points on the circumference of the circle without passing through the center. If the line passes through the center of the circle, it is a diameter. To calculate the chord length, you need to know the radius and either the central angle or th...
Now to calculate the circumference of the circle we multiply pi (∏) by the diameter (d) of the circle. ∏ is a fixed value equal to 3.14, or to be exact 3.1415926535897932384 but = 3.14 will do for our calculations. Calculating the circumference using diameter. We now know what the dia...
To calculate circumference, then, you multiply the circle's radius by 6.28. Take a circle with a radius of 4 inches. Multiplying the radius by 6.28 give you 25.12. So the circle's circumference is 25.12 inches. Calculating Area You can also calculate the area of a circle using the circle...
You can convert the formula for area of a circle to calculate area using the circle's diameter,d. Since 2r=dis an unequal equation, both sides of the equal sign must be balanced. If you divide each side by 2, the result will ber=d/2. Substituting this into the general formula for ...

measurement. Perhaps measuring a straight line through the center of a circle would be difficult because of scale or accuracy, but the circumference could be a known value or easier to measure precisely. In these scenarios, we can use these equivalencies to then find diameter, radius, and area...
Calculate the area of a Circle in Excel The area of a circle is 3.14*(radius*radius). To create the formula in Excel, I could suggest the exponential function however, since the goal is just to find the square, we can twist the formula a little. The syntax to find the area of a ...

You can also calculate the area if a circle if you know the radius. So, if you have a radius of 4.5 inches: A = π * 4.5^2 A = 3.14 * (4.5 * 4.5) A = 3.14 * 20.25 A = 63.585 (which rounds to 63.56) A = 63.56 square centimeters ...
