Both stars are the same color. The nearer star is known to have a radius 3 times that of our sun. How many times the sun's radius is the farther star?

Data is insufficient to tell. If something could be said about the apparent brightness of the stars, a computation could be made.

If you use the HD diagram (diagram we use in astronomy to map brightness of stars) you notice that the curve is exponential. So, since the factor on the HD diagram is ^2 power, you can conclude that the radius of the farther star is 9 times that of the closer star. As to not having enough data, the color indicates that the relative temperature of the stars is the same, and so absolute magnitude (how bright the star is) can be determined. Hope this helps!!

From the information given all you can do is assume that stars with the same color have about the same radius. So the answer would be 3 X

Most likely 3 times.

No it gained't because what led to the sky to blue is the picture voltaic interacting with the ambience. If the blue movie star produces a similar gentle shades that are pink, orange, yellow, eco-friendly, blue, and violet because the yellow movie star. The sky will nonetheless be blue.
