Sphere Calculator: Find Volume, Surface Area, and Diameter

Your details

Choose which property you already know. Enter its value below.
The distance from the centre of the sphere to its surface.
m
Volume (V)
523.5988m³

Total three-dimensional space enclosed by the sphere: V = (4/3) x pi x r^3

Surface area (A)314.1593m²
Diameter (d)10m
Radius (r)5m
Circumference (C)31.4159m
Surface-to-volume ratio (A/V)0.6

Sphere with radius 5.000 m

  • The sphere has a radius of 5.000 m, a diameter of 10.000 m, and a circumference of 31.416 m.
  • Its surface area is 314.159 m^2 and its volume is 523.599 m^3.
  • The surface-to-volume ratio is 0.6000 per m. Smaller spheres have higher ratios, which is why small cells lose heat and exchange nutrients more efficiently per unit of volume than large ones.
  • Among all 3D shapes with the same surface area, the sphere encloses the greatest volume. This is why soap bubbles are spherical.

Next stepUse the "I know the" selector to reverse-solve: enter a volume, area, or circumference to find the corresponding radius and all other dimensions.
