A student estimates the diameter of the moon 3,474 kilometers. If the moon were made of green
Cheese, how many cubic kilometers of cheese would there be?

Question

Quizplus · Accepted Answer

The volume of a sphere is (4/3)πr^3, where r is the radius. We know that the diameter is 3,474 kilometers, so the radius is half of that, which is 1,737 kilometers. Plugging this into the volume formula, we get (4/3)π(1737)^3, which is approximately 21.97 x 10^9 cubic kilometers. Since our answer choices are in scientific notation, we look for the one closest to 21.97 x 10^9, which is C.
