Explanation:

Step1: Recall the relationship between radius and diameter

The formula for the radius \(r\) of a circle in terms of its diameter \(d\) is \(r=\frac{d}{2}\).

Step2: Substitute the given diameter value

Given \(d = 2\) feet. Substitute \(d = 2\) into the formula \(r=\frac{d}{2}\), so \(r=\frac{2}{2}\).

Step3: Calculate the radius

\(\frac{2}{2}=1\).
