How to Calculate Sphere Volume in Imperial Units
Determine sphere volume using radius or diameter in inches or feet. Formula: V = (4/3)πr³.
Example: a spherical tank 6 feet in diameter holds about 113 ft³ (846 gallons). A 12-inch diameter ball has a volume of 0.52 ft³ (3.9 gallons).
Useful for spherical storage tanks, exercise balls, globes, and round vessels.
