Circle line length formula
WebSep 15, 2024 · Theorem 2.5. For any triangle ABC, the radius R of its circumscribed circle is given by: 2R = a sinA = b sin B = c sin C. Note: For a circle of diameter 1, this means a = sin A, b = sinB, and c = sinC .) To prove this, let O be the center of the circumscribed circle for a triangle ABC. WebFeb 2, 2024 · Use an adequate formula to solve your problem. In this case, it would be r = c/(2π). Input the circumference in the formula. The result should be: r = 10cm / (2π). Double-check your results. Input 10 cm in the circumference box of the circle length calculator. The result should also be 1.59155 cm for the radius.
