C = 2 × π × r. For the given sphere, r = 5 cm. Therefore, circumference of the given sphere = 2 × 3.14 × 5 = 31.4 cm. Example 2: If the radius of a sphere is 10 cm, find its surface area. Solution: We know that the surface area of a sphere is given by. Surface Area = 4 r2. For the given sphere, r = 10 cm.
5 days ago · A sphere is defined as the set of all points in three-dimensional Euclidean space R^3 that are located at a distance r (the "radius") from a given point (the "center"). Twice the radius is called the diameter, and pairs of points on the sphere on opposite sides of a diameter are called antipodes. Unfortunately, geometers and topologists adopt incompatible conventions for the meaning of "n ...

Dec 29, 2023 · Sphere Formulas. When we look at a sphere, some of the fundamental measures that describe it are its surface area and volume. The formula for the surface area of a sphere is 4πr², where r represents the radius of the sphere. The formula for the volume of a sphere is 4/3πr³. These formulas are essential in calculating various properties of a ...
