Explanation:

Step1: Identify the given values

We know the equation is \( y = 2x \), where \( x \) is the radius (5 inches) and \( y \) is the diameter.

Step2: Substitute \( x = 5 \) into the equation

Substitute \( x = 5 \) into \( y = 2x \), so \( y = 2\times5 \).

Step3: Calculate the result

\( 2\times5 = 10 \).

Answer:

10
