This is one of those questions where, if you know the formula, it's easy,
and of you don't know the formula, there's no way.
In fact, the whole purpose of the question is to help you remember the formula.
The volume of a cylinder is
(pi) x (the radius)² x (the height).
For this particular cylinder, that's
(pi) x (3)² x (10) =
(pi) x (9) x (10) = 90 pi cubic units.
If you use (3.14) for (pi), then that's <em>282.6 cubic units</em>.
3384 because .88 times 1800 is 1584 and you have to add that to 1800 making it 3384 (or the questions is really easy and its just 1800.88)

Answer:
3 divided by 4 is 0.75
Step-by-step explanation:
Answer:
P(A)=0.55
P(A and B)=P(A∩B)=0.1265
P(A or B)=P(A∪B)=0.7635
P(A|B)=0.3721
Step-by-step explanation:
P(A')=0.45
P(A)=1-0.45=0.55
P(B∩A)=?
P(B|A)=0.23
P(B|A)=(P(A∩B))/P(A)
0.23=(P(A∩B))/0.55
P(A∩B)=0.23×0.55=0.1265
P(A∪B)=P(A)+P(B)-P(A∩B)
=0.55+0.34-0.1265
=0.7635
P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721
