Question

Is sphere, a \[2{\text{D}}\] or a $3{\text{D}}$ object?

Answer 1

Hint: From the question, we have to say whether the given geometric shape, the sphere is either\[2{\text{D}}\] or $3{\text{D}}$. For that, first we have to know about the two dimensional and three dimensional phase then we draw a given geometric shape on the graph with axes. Clearly, it shows that the given geometric shape is two-dimensional or three dimensional. So, we have to conclude the required result by the graphical structure of the given geometric shapes.

Complete step-by-step solution:
First, we have to know about $2{\text{D}}$ and $3{\text{D}}$ terms briefly and they are given below in the following.
$2{\text{D}}$ shapes stand for $2$ dimensional shapes. It has only two measurements that are length and breadth.
Examples for $2$ dimensional objects are square, rectangle, etc.
$3{\text{D}}$ shapes stand for $3$ dimensional shapes. It has three measurements that are length, breadth and height.
Examples for $3$ dimensional objects are cube, etc.
First, we have to know the difference between the circle and the sphere.
A circle is a closed curved line. Each point on this curve line is on the same distance from the focal point (centre) of the circle. In simple terms – a circle is a round object in a plane. A sphere is a round object in a space.

To verify, that the sphere is either a $2$ dimension or a $3$ dimension by the following graphical representation.

Therefore, a sphere is a geometrical object in perfectly round three dimensional shape similar to a round Ball you might play sport with it.
Additionally, we note that every point on the surface of a sphere is the exact same distance from the centre.

Sphere is a 3D object.

Note: First, the students should understand the $2$ dimensions and $3$ dimensions without any doubts. Because this question only depends on finding the given geometrical shapes are $2$ dimensions or $3$ dimensions. Therefore students must know these dimensions concept to find the correct solution. And also they should concentrate on the graphical structure of geometric shapes.
