• Volume of a Sphere: V = 4/3πr³

Explanation:

Step 1: Define

Radius r = 8 cm

Step 2: Find V

1. Substitute [VS]:                    V = 4/3π(8 cm)³
2. Exponents:                           V = 4/3π(512 cm³)
3. Multiply:                                V = (2048/3)π cm³
4. Multiply:                                V = 2144.66 cm³
5. Round:                                  V ≈ 2144.7 cm³
