A sphere is a perfectly round three-dimensional shape where every point on its surface is equidistant from the center. The volume of a sphere is given by V = (4/3)πr³. Spheres are ubiquitous in science and engineering — from balls and bubbles to planets and atoms. The sphere has the remarkable property of enclosing the maximum volume for a given surface area, which is why soap bubbles are spherical. Archimedes considered his proof of the sphere's volume to be his greatest achievement, and he asked that a sphere inscribed in a cylinder be engraved on his tombstone. This calculator provides the volume instantly for any radius, which is useful in applications ranging from calculating the amount of liquid in a tank to determining the volume of celestial bodies.

• !Using the diameter instead of the radius — remember to divide the diameter by 2.
• !Forgetting the (4/3) coefficient.
• !Confusing surface area (4πr²) with volume ((4/3)πr³).
