Answer:
C.
Step-by-step explanation:
Because there is constant term 4 in the question, but there is no any such constant term in the given options.
The conditional, <span>If four points are non-coplanar, then they are non-collinear, </span>is true:
This is, coplanarity is a necessary condition to be collinear.
The converse, <span>If four points are non-collinear, then they are non-coplanar, is false.
A counterexample that disproves this statement is the 4 vertices of a paralelogram, of course they are in a same plane and are not collinear.

Given that the radius of the circle is 6 cm.
The central angle is 120°
We need to determine the length of AB.
<u>Length of AB:</u>
The length of AB can be determined using the formula,
Substituting and in the above formula, we get;
Simplifying the values, we get;
Substituting π = 3.14, we have;
Thus, the arc length of AB is 12.56 cm
