If the Earth were flat, the entire ship would remain in view, and just get smaller and smaller. And that is what they saw. If you travel to a different latitude, you will notice that the star patterns change. If, for instance, you moved across the surface of a flat Earth, you would always be able to see the North Star, Polaris.
However, such is not the case. When you travel below the equator, Polaris is no longer visible. Get a free answer to a quick problem.
A sphere is a three-dimensional geometric shape that is formed by joining an infinite number of points located at a fixed distance from a central point.
The distance between a point located on the surface of the sphere and the centre is known as the radius. A sphere does not have edges or vertices. In simpler terms, a sphere geometric shape can be formed by spinning a circle along its diameter.
Among all the three-dimensional shapes with the same surface area, the sphere tends to have the maximum capacity or volume. Balls used in a number of bowling games are a prominent example of a sphere geometric shape. Example 1: Find the diameter and circumference of a sphere with a radius of 7 units. Therefore, the diameter and the circumference of the given sphere are 14 units and 44 units respectively. Substituting the value of radius in the formula, we get,.
Example 3: Find the surface area of a sphere whose radius is 5 units. A sphere is a three-dimensional object with no vertices and edges. Some real-world examples of a sphere include a football, a basketball, the model of a globe.
Since a sphere is a three-dimensional object it has a surface area and volume. The distance of a line segment that connects two opposite points on the surface of the sphere passing through its center is called the diameter of a sphere. The diameter of a sphere is two times its radius.
The surface area of a sphere is the area occupied by the surface of the sphere. In simple words, the amount of material used to cover the outer part of a sphere gives its surface area.
The volume of a sphere is the amount of space occupied by the sphere. For example, imagine a spherical balloon. The amount of air inside the balloon is its volume. A face is referred to as a flat or curved surface on a three-dimensional object.
For instance, a cube has 6 faces. Thereby, a sphere has only one face which is a curved surface. It does not have any flat faces. A circle and a sphere are different objects. Since both of them are circular in shape, it creates a notion as if the two shapes are similar. The differences that outline that both are different objects are as follows. Yes, a sphere is a three-dimensional object that occupies three axes, which are the x-axis, y-axis, and z-axis.
It has a surface area and a volume like any other three-dimensional object. A sphere is a three-dimensional object that is perfectly spherical in shape. The radius of the sphere is the same at all points of the sphere from its center, whereas, a spheroid resembles a sphere but the radius is not the same at all points from the center of a spheroid.
