Sphere Calculator
Calculate the volume, surface area, and other dimensions of a sphere using its radius.
Sphere Volume and Surface Area Calculator
Calculate the volume and surface area of a sphere with our easy-to-use calculator. Learn about sphere formulas, real-world applications, and explore interactive examples.
A sphere is a perfectly round three-dimensional shape where every point on its surface is equidistant from the center. Our sphere calculator helps you determine both the volume and surface area of a sphere using just its radius. Whether you're working on a math problem, designing a spherical container, or calculating the size of a ball, this calculator provides quick and accurate results.
Formula
Volume = (4/3)πr³
Surface Area = 4πr²
Where:
- r:radius of the sphere (in your chosen unit of length)
- π:pi, approximately equal to 3.14159

Frequently Asked Questions
What is the difference between area and volume?
Area measures the size of a surface in square units (like the surface of a sphere), while volume measures the amount of space inside a three-dimensional object in cubic units.
How does doubling the radius affect volume?
When you double the radius of a sphere, the volume increases by a factor of 8 (2³).
