WebMar 24, 2024 · A sphere is defined as the set of all points in three-dimensional Euclidean space that are located at a distance (the "radius") from a given point (the "center"). Twice the radius is called the diameter , … WebYou do need to be more specific, the volume of a sphere is V = 4/3 π r^3, it does not need to be related to a cylinder. So if you know the radius, you can calculate the volume. The volume of a cylinder with the same radius and with a height of 2r (since it would be the diameter across) would be V = π r^2 h = 2π r^3. Webcylinder sphere In geometry terms the difference between cylinder and sphere is that cylinder is a solid figure bounded by a cylinder and two parallel planes intersecting the cylinder while sphere is the set of all points in three-dimensional Euclidean space (or n -dimensional space, in topology) that are a fixed distance from a fixed point . 3 英语翻译
