Easily calculate the volume and surface area of any sphere. Enter the radius or diameter to get instant results with steps.
A sphere is a perfectly round geometrical object in 3D space. To calculate its properties, you only need the **radius (r)**.
V = (4/3) × π × r³
A = 4 × π × r²
Follow these simple steps:
Calculate the volume of a soccer ball with a radius of 11 cm.
The diameter is the distance across the sphere through the center. The radius is the distance from the center to the edge. Radius = Diameter / 2.
No, this calculator is for full spheres. For a hemisphere, calculate the volume of a full sphere and divide by 2.
You can use any unit (cm, inches, meters, feet). The result will be in cubic units of whatever you entered (e.g., cubic inches, cubic meters).
