Answer:
The length of the arc is 0.333
Step-by-step explanation:
The length of the circumference is 6
A circle has 360° in total
So to know what fraction the 20° represent we have to divide it by 360°
20° / 360° = 1/18
This fraction if we multiply it by the circumference we will obtain the length of the arc
1/18 * 6 = 0.333
The length of the arc is 0.333
Binary Operations
The union of two sets A and B is denoted A ∪ B and
is defined as A ∪ B = {x|x ∈ A or x ∈ B}.
The intersection of two sets A and B is denoted A∩B
and is defined as A ∩ B = {x|x ∈ A and x ∈ B}.
Two sets are disjoint if they have no elements in common,
that is, A and B are disjoint if A ∩ B = ∅.
