Because that way you can find the answer when you are given a large amount of information and you don't have to guess until you get the answer right.
Answer:
It repeats over and over..
Step-by-step explanation:
Do the volume of a circle then multiply by the length of the cylinder
area of a circle =

diameter/2 = radius
so 4^2 = 16 16*3.14 = 50.24
50.24*(4*3) = 50.24*12 = 602.88
Whether~1.F(x)*G(x),
2. F(x)+G(x),
3.F(G(x)),
4.F(x)=G(x) ?
