< b="" />Explanation: < />
To obtain a sphere, we need to follow the process of rotating a semicircle about its diameter. Let's break down the process step by step:
< b="" />Step 1: Draw a semicircle:< />
Start by drawing a semicircle on a piece of paper or any other flat surface. A semicircle is half of a circle, which means it has a curved edge and a straight edge. The curved edge is called the arc, and the straight edge is called the diameter.
< b="" />Step 2: Place the semicircle on a flat surface:< />
Place the semicircle on a flat surface such that the straight edge (diameter) is touching the surface. This will allow us to rotate the semicircle easily.
< b="" />Step 3: Rotate the semicircle:< />
Hold the semicircle firmly at the diameter and rotate it continuously in a circular motion. Make sure the semicircle rotates in a complete circle, covering 360 degrees.
< b="" />Step 4: Observe the shape:< />
As you rotate the semicircle, pay attention to the shape that is formed. You will notice that the shape gradually transforms into a three-dimensional object. This three-dimensional object is known as a sphere.
< b="" />Conclusion:< />
By following the process of rotating a semicircle about its diameter, we can obtain a sphere. The rotation allows the two-dimensional semicircle to transform into a three-dimensional shape, giving us a sphere.
