The circular arc of a railroad curve has a chord of length 3100 ft. corresponding to a central angle 39 degrees(round your answer to two decimals) A) Draw a diagram that visuallyrepresents the sitiuation. Show the known quanitities on the diagram and use the variables r and s to represent the radius of the arcc and the length of the arc. B) Find the radius r of the circular arc C) Find the length s of the circular arc
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
