Final answer:
The radius of the given circle is 1 unit.
Step-by-step explanation:
The equation given is (x - (11/4))^2 + y^2 = 1. This equation represents a circle with its center at the point (11/4, 0) and radius 1 unit. To find the radius of the circle, we can compare the equation to the standard form of a circle, (x - h)^2 + (y - k)^2 = r^2. In this case, h = 11/4, k = 0, and r = 1. Therefore, the radius of the circle is 1 unit.
