There is a circular track of length 400 m. If you are running around the circumference and at an angle of 270° from the centre, what is the length you have covered while running?
300 m
If you run for 400 m, angle subtended at the centre will be 360°
Similarly, For 180∘, length covered = 200 m
For 90∘, we can now say that length covered will be 100 m
So, for 270∘=180∘+90∘, length covered = 200 m + 100 m = 300 m
