Who among the following (an ant, a mouse or a man) could be able to creep under it?

Question

The circumference of the Earth is around 40,075 km.

If we made a circle of a wire around the globe, that is only 10 meters (0.01 km) longer than the circumference of the globe;

Who among the following (an ant, a mouse or a man) could be able to creep under it?

Answer 1

Circumference (40,075 km) = 2 * π * Radius
using π value as 3.142857 if we solve the equation for R we get 6375.568182 Kms radius.

now increasing the circumference by 0.01 km we solve again to get new radius
Circumference (40075.01 km) = 2 * π * Radius
the new R we get 6375.568182 Kms.

The difference will be the increase in height clearance = 1.590909 mtrs
Meaning All of above can creep under the wire..
