A Correct answer
Explanation

The volume of a sphere is (4/3) * pi * r^3. With r = 7 and pi = 3.14, V = (4/3) * 3.14 * 343 = 1436.0266... which rounds to 1436.03.

AI explanation

We use the sphere volume formula, which is (4/3) pi r cubed, substituting 7 cm for the radius and 3.14 for pi. This gives (4/3) times 3.14 times 343, which calculates to 1436.03 cubic cm.
