WebFeb 2, 2024 · The radius of a circle from the area: if you know the area A, the radius is r = √ (A / π). The radius of a circle from circumference: if you know the circumference c, the radius is r = c / (2 * π). The radius of a circle from diameter: if you know the diameter d, the radius is r = d / 2. WebWhich is true regarding secants and chords? Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle. In circle O, AD and BE are diameters. The measure of arc AB is 55° and the measure of arc CD is 25°. What is the measure of EAC ... Web27 In the diagram below of circle O, diameter AB and radii OC and OD are drawn.
