If the radius and arc length of a circle are given, the angle in radians can be obtained by dividing arc length by the radius. However, the arc length and the radius should be in the same units. Answer and Explanation: The following are given...

In the arc system, if the central angle of the arc is θ, then there is a formula L=Rθ. The fan area formula S=LR/2, corresponding to the fan area calculation formula \(S=RRθ/2\) In a circle, the line connecting the center of the circle and any point on the circle is call...
