Step 1: Recall the formula for the circumference of a circle.
The formula for the circumference of a circle is $$C = 2πr$$, where $$C$$ represents the circumference and $$r$$ represents the radius.
Step 2: Plug in the given circumference value into the formula.
So, we have $$18~\text{in} = 2πr$$.
We are given that the circumference is 18 inches.
Final Answer
The radius of the circle is approximately 2.82 inches and the diameter is approximately 5.65 inches.
