Sphere Calculator

Use our free sphere calculator to compute the surface area and volume of a sphere. Enter the radius.

Math

Radius (r)

Formula

A sphere is a perfectly round 3D object with all surface points equidistant from the center.

A = 4πr², V = 4/3 πr³

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter the radius.
2Click Calculate.

Examples

Sphere radius 5

1.r=5.
2.SA=4π×25≈314.16, V=4/3π×125≈523.60.

Result: SA: 314.1593, V: 523.5988

Sphere radius 10

1.r=10.
2.SA=4π×100≈1256.64, V=4/3π×1000≈4188.79.

Result: SA: 1256.6371, V: 4188.7902
