Our online calculator provides an easy way to determine the volume and surface area of a sphere. Simply enter the radius of your sphere and the calculator will quickly display the results.
A sphere is a three-dimensional shape that is symmetrical and has no flat surfaces or corners. Every point on the surface of a sphere is equidistant from its center. This distance r is a positive real number called the radius of the sphere. The sphere has the smallest surface area among all surfaces enclosing a given volume and it encloses the largest volume among all closed surfaces with a given surface area.
The concept of spheres has a rich history, with ancient civilizations such as the Greeks and Romans using them for decoration and navigation.
Whether you're a student, researcher, or simply curious, our calculator is a reliable tool for calculating the volume and surface area of a sphere. Try it now and discover the measurements of your sphere.
The calculator uses the following formulas for the volume and the surface area:
