answer: it is correct :The equation is not quadratic in for because it cannot be written as a second degree polynomial
explanation : if the leading term had x^2, then it would be quadratic, but it's not
The last one is the correct answer
The volume of a cylinder is found with V=pi*r^2*h
The radius is 9 (18/2)
We can plug in what we know to find the volume
V=pi*9^2*3
V=pi*81*3
V=243*pi
Hope this helps

Translating the given problem
into equation form:
Let A = volume of prism A
B = volume of prism B
C = volume of prism C
Eqn 1: A + B+ C = 518
Eqn 2: A = (1/3)B
Eqn 3: B = C
There are 3 equations and 3
unknowns, the system of linear can be solved. Using a calculator (preferably Casio
991-ES), yields:
A = 74 cu.ft
B = 222 cu.ft
C = 222 cu.ft
