Questions & answers

What does Sphere Volume & Surface Calculator calculate?

Calculate a sphere’s capacity and exterior area from its radius.

Which units should I enter?

Radius uses cm. Convert values to these units before calculating.

Which formula does it use?

Volume = 4πr³/3; surface = 4πr².

What does the included example show?

Radius: 5 cm. Result: Volume · cm³ = 523.59878; Surface area · cm² = 314.15927; Capacity · liters = 0.52359878.

Can I compare different settings?

Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.

Can I export the calculation?

Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
