Considerng the Earth as a perfect sphere with no mountains.
Imagine a rope running around the Equator at the surface level and another rope running just one meter higher. How many meters longer will the higher rope be?

it will be 6.28 meters longer, as you increased the diameter by 2 meters. it doesn't matter one bit what the original diameter is. you don't need to know what the diameter is to know how much longer the second rope will be, it will always be 6.28 meters long, whether you started with a ten meter diameter, or a 10,000 meter diameter

first circumference would be (pi)d
the second would be (pi)(d+2)
d=diameter of earth.
Have to add two for the meter added on both sides.
The problem is you have to do several steps to get a value for d. The earth has two diameters: polar and equatorial. It bulges at the equator due to its spin. The equatorial diameter is approx 7,926miles and the polar diameter 7,900 miles.
Have fun. Oh yeah, and d would have to kept in meters for the calculations since you are adding 2 meters to it for the second result.

2 pi
you work out the explanation yourself
