The surface area of the Earth is approximately 510.1 million square kilometers. This can be calculated using the formula for the surface area of a sphere: 4πr², where r is the radius of the Earth (about 6,371 kilometers).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
