Answer:
The answer is "
"
Step-by-step explanation:
Given:

In the scale factor when we take x coordinate then the value of k is:
If we take y coordinate then the value of k is:

So, the final value of k is "
" .
Circumference=2pi*r
20.7=2pi*r
r=3.296 or 3.3
A=pir^2
a=34.1946 or about 34.19
Answer: 100 x
Step-by-step explanation:.
514 divided by 28 equals 18.3571429
The inclusion/exclusion principle states that

That is, the union has as many members as the sum of the number of members of the individual sets, minus the number of elements contained in both sets (to avoid double-counting).
Therefore,

will have the most elements when the sets

and

are disjoint, i.e.

, which would mean the most we can can in this case would be

(Note that

denotes the cardinality of the set

.)
