Detailed Solution

Concept- To ascertain the number of semicircles present within a circle. Let's define a circle first. We are aware that a circle is a figure with a circular shape and no corners or edges. A circle's centre is the point on the circumference from which all distances to other places on the circle are equal. This distance is referred to as the radius. A full circle is divided in half by a line segment that passes through the centre of the circle to create a semi-circle. The diameter of the circle is something that we refer to as this line segment. The diameter at which the circle is divided into two equal pieces.
We need to determine how many semi circles make up a circle. Let's define a circle first.
We are familiar that a circle is a figure with a circular shape and no corners or edges. A circle is, in other words, a closed, curved, two-dimensional shape.
Let's now think about a circle's centre and radius. The point in the middle of a circle from which all distances to the other points on the circle are equal is known as the centre of the circle. This distance is referred to as the radius. The figure below shows this.

The circle in the above figure has A as its centre.
The radius is indicated by AC in the figure below.

Let's now define a semicircle. A full circle is divided in half by a line segment that passes through the centre of the circle to create a semi-circle. The diameter of the circle is where we refer to this line segment. A circle's diameter is equal to twice its radius. On the following page, this is displayed.
Question Image

As seen in the figure above, AD is the diameter that divides the circle into two equally sized sections that we refer to as semicircles.
Thus, there are 2 semi circles within a circle.
Hence, the correct answer is option (2).
