of the full area. Remember the area of a circle = \(\pi r^2\) The sector area is: \(\frac{1}{6} \times \pi \times 4^2 = 8.4~\text{cm}^2\) The formula to calculate the sector area is ...

It also separates the circle into two segments - the major segment and the minor segment. The formula to calculate the arc length is: \(\text{Arc length} = \frac{\text{angle}}{360^\circ} ...
