A sphere is 3-dimesnional geometrical shape which is said to be perfectly rounded. A sphere is just like a circle in which all the set of points is on equal distance (r) from the centre but in 3D space.
Properties of Sphere
- A sphere is perfectly symmetrical shape.
- There are no edges or vertices in a sphere.
- All the points on a sphere are on same distance from the centre that is radius (r).
- Sphere has one surface.
Surface Area of Sphere
Surface area of sphere is given by the formula.
S.A = 4 × π × r²
Volume of Sphere
Volume of sphere is given by the formula,
V= (4/3) × π × rᶾ
