Calculating the total area of your pizza is easy with the right formula. Maksim Denisenko/Shutterstock Use the following formula to calculate circle area: A = πr². Simply square the length of the radius (r), then multiply that number by pi (π). Let's clarify a few things. A cir...
Using the Arc Length formula (in degrees) As we stated before, when you form a central angle θ°, it intercepts an arc on the circumference of a circle. This intercepted arc has a measure equal to that of your central angle θ°. If the intercepted arc length is known, then finding ...
67. What is a Central Angle Formula? Central Angle Measure = (Arc Length / Radius) * 180° Central Angle Measure = (Arc Length + Radius) * 180° Central Angle Measure = (Arc Length - Radius) / 180° Central Angle Measure = (Arc Length * Radius) * 180° ...
