Calculating the circumference using the radius. If we have the radius of a circle then to calculate the circumference we multiply pi (∏) by the radius (r) of a circle and then multiply by 2. For the circle above we have a radius (r) of 5cm, so lets calculate the circumference: And...
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...

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 ...
Equation for Bolt Circle Diameter: BCD equation. D is the BCD, N is the number of holes and A is the hole spacing © Eugene Brennan Working Out the BCD for a Chainring or Bash Guard All you need to do to calculate the BCD is measure the hole spacing A between adjacent holes, coun...
A = 56.71625, which rounds to 56.72 A = 56.72 square centimeters 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 ...
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...
How To Calculate Arc Area The Most Dangerous Animal In A Zoo Isn't A Lion An arc is a curved area of a circle that makes up part of its circumference. If you know the arc of a circle, you can measure the area enclosed by this arc plus two lines that extend from the center of ...
