Question

find the area of this sector if ( r = 2 ) and ( \theta = \frac{pi}{9} ) radians.
( \frac{?}{} pi ) sq units

Explanation:

Step1: Recall the formula for the area of a sector

The formula for the area of a sector is \(A=\frac{1}{2}r^{2}\theta\), where \(r\) is the radius and \(\theta\) is the central angle in radians.

Step2: Substitute the given values into the formula

Given \(r = 2\) and \(\theta=\frac{\pi}{9}\), we substitute these into the formula:
