Arcs are an important aspect of geometry, physics, trigonometry and design work. However, curved lines are much more difficult to measure than straight lines, which is why it's important to ...

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, ...

The circumference of a circle = \(\pi d\) or \(2\pi r\). Look at the sector of the circle shown below. To calculate the length of the arc, we need to know what fraction of the circle is shown. To do ...
