Answer: 7776\pi units^{3}

Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of sphere.

Volume = \frac{4}{3} \pi r^{3}

Notice that our sphere has a radius of 18 units, so we can plug 18 into the formula.

Volume = (\frac{4}{3}\))\pi(18units^{3})

Now, let's start by simplifying the exponent. 18^{3} is equal to 18 units x 18 units x 18 units or 5,832 units³.

Volume = (\frac{4}{3}) (5,832 units^{3}) (\pi)

Notice that we can cross cancel 3 in \frac{4}{3} and 5,832 to 1 and 1,944.

Volume = (4) (1,944 units^{3})(\pi)

Volume = 7776\pi units^{3}

Let a = {1, 2, 3, 4, 5} b = {1, 3, 5} c = {4, 6}. find the cardinality of the given set. 33. n(a) 34. n(b) 35. n(a ⋃
bearhunter [10]

1) n(a) = 5


The cardinality of a set is the number of elements in that set. So, you simply need to count how many elements belong to the set, and the answer is 5


2) n(b) = 3


Simlarly, in this case you need to count how many elements belong to the set, the answer is 3


3) n(a ⋃ c) = 6


The union of two set is a set composed by all the elements belonging to either one of the sets, with no repetitions. So, since the first set contains all numbers from 1 to 5, the second set contains a 4, which however already belonged to the first set, but also a 6, which is added in the union. So, a ⋃ c = {1,2,3,4,5,6}, and thus n(a ⋃ c)=6.


4) n(a ⋂ c) = 1


The intersection of two sets is a set composed by the elements belonging to both sets. So, 1,2,3 and 5 don't belong to the intersection, because they belong to the first set alone, while 6 doesn't belong to the intersection because they don't belong to the first one. So, a ⋂ c = {4}, and thus n(a ⋃ c)=1.
