Question

what is the diameter of this circle?

Explanation:

Step1: Identify circle's endpoints on x - axis

The circle intersects the x - axis at approximately \(x = 6\) and \(x = 10\).

Step2: Calculate diameter

The diameter \(d\) is the distance between these two points. Using the formula \(d=x_2 - x_1\), where \(x_1 = 6\) and \(x_2=10\), we have \(d = 10 - 6=4\).
