A central angle is an angle with a vertex at the centre of a circle, whose arms extend to the circumference. You can imagine the central angle being at the tip of a pizza slice in a large circular pizza. You can find the central angle of a circle using the formula: θ = L / r. where θ is the central angle in radians, L is the arc length and r ...

Example 1: Find the central angle, where the arc length measurement is about 20 cm and the length of the radius measures 10 cm? Solution: Given r = 10 cm. Arc length = 20 cm. The formula of central angle is, Central Angle θ = \[\LARGE \frac{Arc Length \times 360}{2 \times\pi \times r}\] Central Angle θ = \[\LARGE \frac{20 \times 360}{2 \times 3.14 \times 10}\]
