Divide the circumference by 2 for 8.5 inches diameter
8.5^2*pi= <span>226.98 inches squared</span>
PN = LO
__________________________
(LO)^2 = (LN)^2 + (NO)^2
(LO)^2 = 6^2 + 8^2
(LO)^2 = 36 + 84
(LO)^2 = 100
LO = √100
LO = 10
__________________________
Thus :
PN = 10
The correct answer is: D. (A u B)
Step-by-step explanation:
The operations on sets are of two types
1. Union
2. Intersection
In union, the elements of both sets are combined in one set while in intersection only common elements of both sets are considered.
Here,
"all of the elements which are in set A or B"
This statement means the elements of both sets have to be considered. The word "Or" points to the combination of both sets as an elements belonging to any of the set will be considered. So union operation will be used.
Hence,
The correct answer is: D. (A u B)
