Answer:
3 Packs of 3 Rolls & 1 Pack of 1 Roles
Step-by-step explanation:
3 x 25.38 = 76.14
76.14 + 9.21 = $85.35
But if you do 2 packs of 5 rolls
42.85 x 2 = $85.70
SO THE TOP ANSWER IS CORRECT
I think I know what it forms - a cone!!
I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees.
Line AB would be the radius of the "upper cone".
Line BC is 12/2 or 6
tangent (A) = BC / AB
tangent (5) = 6 / AB
AB = 6 / tan(5)
AB = 6 / 0.087489
AB =

68.58 which is the radius of the "upper cone".</span></span></span>
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 68.58 * 68.58 * 6) / 3
Cone Volume =

29,551
That is just the "upper cone volume. So, we multiply </span></span></span><span><span>

29,551 * 2
and get 59,102 which is the volume of the entire solid.

Volume = v, height = h, area of the base= B
v=h•b
144=h•48
h=144/48
h=3 inches
A graph in which points representing values of a variable for suitable values of an independent variable are connected by a broken line.
