Sphere Formulas

A sphere is a perfectly round 3D shape where every point on its surface is equidistant from the center.

Volume = (4/3) × π × r³
Surface Area = 4 × π × r²

Common Sphere Examples

r = 3 cm
V ≈ 113.10 cm³
r = 5 m
V ≈ 523.60 m³
r = 7 in
SA ≈ 615.75 in²

Frequently Asked Questions

What is the volume of a sphere with radius 5? ▼
V = (4/3) × π × 5³ = (4/3) × π × 125 ≈ 523.60 cubic units.
What is the surface area of a sphere with radius 3? ▼
SA = 4 × π × 3² = 4 × π × 9 ≈ 113.10 square units.
How is sphere volume different from cylinder volume? ▼
Sphere: V = (4/3)πr³. Cylinder: V = πr²h. A sphere with radius r has volume equal to (2/3) of a cylinder with the same radius and height=2r.
