Circumradius of a Triangle Overview and Equation - Study.com

WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd. C = 2πr. WebThe formula for the radius of the circle circumscribed about a triangle ( circumcircle) is given by R = a b c 4 A t where A t is the area of the inscribed triangle. Derivation: If you have some questions about the angle θ shown in the figure above, see the relationship between inscribed and central angles.
