Consider the circle of radius r=9 cm. A segment in this circle is enclosed by a chord AB and a minor arc AB. The chord AB has length 5 cm, first find what is the length of the minor arc AB and then calculate the perimeter of that segment. Give your answer for the perimeter of the segment in cm correct to 2 decimal places (enter only the number without units).
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.
