The formula to calculate the Angle of Circular Sector (∠Sector) is:
\[ \angle_{\text{Sector}} = \frac{l_{\text{Arc}}}{r} \]
Angle of Circular Sector is the angle between the radial edges of a Circular Sector or the central angle in which a circle is cut to form the Circular Sector. Arc Length of Circular Sector is the length of the curved boundary edge of the Circular Sector. Radius of Circular Sector is the radius of the circle from which the Circular Sector is formed.
Let's assume the following values:
Using the formula:
\[ \angle_{\text{Sector}} = \frac{4}{5} = 0.8 \]
The Angle of the Circular Sector is approximately 0.8 Radian.
