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
.)
Answer:
5.23 < 5.235
Step-by-step explanation:
5.23 < 5.235
we know:
5.235 ≈ 5.24
hence 5.235 is greater than 5.23
This is the derivative of S with respect to r, evaluated at r=8.
dS/dr = 8πr
Substituting r=8 into the above gives the answer of 64π.
Volume= Length • Width • Height
