Arc length can be calculated with the help of the central angle of that arc and the radius of the circle to which that arc belongs. The unit of the central angle can be in degrees or radians. So, ...

Calculate the arc length to 2 decimal places. First calculate what fraction of a full turn the angle is. 90° is one quarter of the whole circle (360°). Therefore, the arc length is \(\frac{1}{4}\) of ...

A chord separates the circumference of a circle into two sections - the major arc and the minor arc. It also separates the circle into two segments - the major segment and the minor segment. The ...
