The surface area of a sphere is given by the formula A = 4πr^2, where r is the radius of the sphere.
Given that the radius of the sphere is 37.68 km, the surface area would be:
A = 4 * π * (37.68)^2
A ≈ 4 * 3.14159 * 1418.5024
A ≈ 4 * 3.14159 * 1418.5024
A ≈ 17713.0286 km2
Therefore, the approximate surface area of the sphere is 17,713 km2.
