Earth has a radius of about 6.4 x 106 m. a.) Approximate the surface area of Earth using the formula for the surface area of a sphere, S=4πr2. b) Earth’s surface is about 70% water, almost all of it in oceans. About how many square meters of Earth’s surface are covered with water? c) The oceans have an average depth of 3795 m. Estimate the volume of water on Earth.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
