If Earth's radius was larger by 1 meter, how much longer would its equator be?

by approx 6 meters
by approx 6 kilometers
by approx 60 kilometers
by approx 6000 kilometers
For each circle, the length of the circumference is c=2πr. Hence, if a radius grows by 1 meter, the circumference grows by 2 π meters - no matter what the initial value of radius was.
