Question

read the description of a proportional relationship. roxanne is measuring the diameter and the radius of different - sized circles. there is a proportional relationship between the radius of the circle in inches, x, and the diameter of the circle in inches, y. the equation that models this relationship is y = 2x. what is the radius of a circle with a diameter of 12 inches? write your answer as a whole number or decimal. inches

Explanation:

Step1: Identify the given equation

The equation is $y = 2x$, where $y$ is the diameter and $x$ is the radius.

Step2: Substitute the given diameter value

We know $y = 12$ inches. Substitute $y$ into the equation: $12=2x$.

Step3: Solve for $x$

Divide both sides of the equation by 2. So, $x=\frac{12}{2}=6$.

Answer:

6
