Practice Problems on Sphere
Some problems on sphere are,
P1: A gas tank has the shape of a sphere with a 14 m diameter. What is the gas tank’s capacity in cubic meters (m³)?
P2: Determine the volume of a volleyball with a radius of 4.5 decimeters, using π as 22/7.
P3: How many times will a sphere’s volume rise if the diameter grows by 10 times?
P4: Calculate the surface area of the sphere given that its volume is 803.84 cubic meters (m3).
P5: Determine the sphere’s surface area. Its volume is 33.9 cubic centimetres (cm3).
Sphere: Definition, Formulas, Examples, Shapes, Properties
Sphere is a three-dimensional object that is perfectly round and symmetrical in shape. It is a set of points in 3-D space that are all equidistant from a fixed point(center). The distance from the center to any point on the surface of the sphere is the same, and this distance is called the radius. A sphere is defined in 3 axis whereas a sphere is defined only in 2 axis.
In this article, we have explained everything about the Sphere from the Definition of Sphere, Volume, and Surface Area Formula, to Real-life Examples of Spheres. Let’s get a closer look at Sphere in Detail.
