A semi-circle is half of a circle, which is typically defined in terms of degrees or radians. Since a full circle is 360 degrees or \(2\pi\) radians, a semi-circle is 180 degrees or \(\pi\) radians.

If we interpret "how many of these make a semi-circle" to mean how many individual angles (measured in degrees or radians) are needed to create a semi-circle, we need more clarification on what "these" refers to.

However, if we consider the simple case where each number represents a certain degree angle, we can combine them to form a semi-circle. None of the numbers you provided alone represents a semi-circle directly, but if you sum them correctly, they could possibly help form a semi-circle in a context depending on how they are used (e.g., summing angles or using them as segments of arcs).

Can you clarify what you mean by “these,” or how they relate to forming a semi-circle?
