Well you are given the roots.
if we have 3 it would.have to be x^3. So something like:
y = ax^3 + bx^2 + cx + d
this could.also be written:
y = (x + a) (x + b) (x + c)
when you are able to write it like this, we know that the opposite of a, b, and c are roots. this is because if we can make any of the insides of the 3 parenthesis equal 0 then y = 0 and that x.is a root. Well if we know the 3 roots that x will be then we just have to figure out the a, b, and c. So let's plug our roots in.
y = (-1 + a) (-5 + b) (-3 + c)
now we have to make each parenthesis equal 0 to find what a, b, and c should be. It is obvious a = 1 to make.that one zero and b = 5 and c = 3. So we know a, b, and c. now let's plug.those into our first equation.
y = (x + 1) (x + 5) (x + 3)
this is your equation. You can multiply out if necessary

Cut it up
1 cylinder and a half sphere
V cylinder=hpir^2
Vsphere=(4/3)pir^3
find each
H=7
r=4
sub
Vcylinder=7pi4^2
V=7pi16
V=112pi
Vsphere (multiply by 1/2 later)
V=(4/3)pi4^3
V=(4/3)pi64
V=(256/3)pi
V=85.33333333333333pi
multply by 1/2 since 1/2 sphere
V=42.6666666666pi
add them
Vclliner+1/2sphere=112pi+42.66666666666pi=154.666666666666pi
pi=3.14 for problem
Vtotal=485.6533333333333333333
hundreth
V=485.65 in^3
600 people could ride because 60 times 10 is 600 and there is 10 half hours in five hours.
