Questions and Answers

Which one of the following statements is true about a circular arc?

The major arc subtends an angle less than π radians. (correct)

The arc of a circle is defined as the part or segment of the diameter of a circle.

A straight line that connects the two ends of the arc is known as a tangent of a circle.

The minor arc subtends an angle greater than π radians.

Which one of the following is the correct formula for calculating the length of an arc of a circle?

L = θ + r

L = θ * r (correct)

L = θ / r

L = θ - r

Study Notes

Circular Arcs and Circles

A circular arc is a part of a circle, which is a two-dimensional shape.
The length of an arc of a circle can be calculated using the formula: L = (θ/360) × 2πr, where L is the length of the arc, θ is the angle of the arc in degrees, and r is the radius of the circle.
A semicircular arc is a half circle, which means it has an angle of 180 degrees.
The circumference of a circle can be calculated using the formula: C = 2πr, where C is the circumference, and r is the radius of the circle.
A chord of a circle is a line segment that connects two points on the circle, and its length is less than the diameter of the circle.
