the speed of light = 299 792 458 m / s or 1079252848800 M/H
circumference = 2*Pi*R
so 2* 3.14159*R= 107925848800M/H
1079252848800/(2*3.14159)=R
Radius= 1.71768571 × 1011(<--- times 10 to the 11th power) meters

Oh No, I'd go with answer number 2 (abinhav or whatever it was) because I once had a physics book with some answers in the back. The question asked somehthing like this...
You are driving at X MPH toward a yellow light. The light will be yellow for X seconds. The intersection X feet long. Can you make it through the light before it turns red. The answer from calculation was No. The answer in the book was "Yes, Speed Up!"
So if you can't go the speed of light the question is nullified

Calculate how far the "spaceship" travels in one hour at the speed of light. That's the diameter of the circle. From that you can calculate the radius. It's physically impossible to travel that fast but that doesn't sound like the issue here.

according to the Theory of relativity no particle could attain the speed of light even if it did its mass would become infinite so u can not define its movement

300,000 km / 3.14 = 95,500 km diameter / 2 = 47,770 km radius
