Question

roxanne is measuring the diameter and the radius of different - sized circles. the graph shows the proportional relationship between the radius of the circle in inches, x, and the diameter of the circle in inches, y. what does the point (4, 8) represent? a circle with a 4 - inch radius has a diameter of 8 inches. a circle with a 8 - inch radius has a diameter of 4 inches.

Explanation:

In a coordinate - graph where the x - axis represents the radius and the y - axis represents the diameter of a circle, each point (x, y) gives the radius and corresponding diameter values. For the point (4, 8), x = 4 (radius) and y = 8 (diameter).

Answer:

A circle with a 4 - inch radius has a diameter of 8 inches.
