Sphere Volume Practice Problems (With Step-by-Step Solutions)

Ten Practice Problems

1. Q1: Find volume with r = 6 cm in terms of π.
   Solution: V = 4/3 × π × 216 = 288π cm³.
2. Q2: A sphere has diameter 12 m. Find volume (π ≈ 3.14).
   Solution: r = 6 m → V ≈ 904.32 m³.
3. Q3: If volume is 36π cm³, find radius.
   Solution: r³ = (36 × 3)/4 = 27 → r = 3 cm.
4. Q4: What happens to volume if radius is doubled?
   Solution: Volume multiplies by 2³ = 8 times.
