Question

the diameter of a circle is 6 inches. what is the area of a sector bounded by a 66° arc? 66° d=6 in give the exact answer in simplest form. square inches submit work it out

Explanation:

Step1: Find the radius of the circle

The formula for the radius \(r\) of a circle given the diameter \(d\) is \(r=\frac{d}{2}\). Since \(d = 6\) inches, then \(r=\frac{6}{2}=3\) inches.

Step2: Use the sector - area formula

The formula for the area of a sector of a circle is \(A=\frac{\theta}{360}\times\pi r^{2}\), where \(\theta\) is the central angle of the sector and \(r\) is the radius of the circle.
We know that \(\theta = 66^{\circ}\) and \(r = 3\) inches. Substitute these values into the formula:
