A Correct answer
Explanation

Volume of a sphere = (4/3) * pi * r^3. With r = 2, V = (4/3) * 3.142 * 8 = (32/3) * 3.142 = 10.666 * 3.142 = 33.51466.

AI explanation

Using the volume of a sphere formula, V equals four thirds times pi times radius cubed, we substitute the radius of 2 to get four thirds times 3.142 times 8. This simplifies to 4 times 3.142 times 8 divided by 3, which calculates to 33.51 cubic meters.
