29. w^2 + 13w + 12
31. 9r^2 - 12r + 4
33. 21q^2 + 62q + 16
The answer is 6/9 as if you multiply 2/3 by 3 you will get 6/9 so it has the same value
We let
r1 = the original radius of the cylinder
r2 = the new radius of the cylinder
h1 = the original height of the cylinder
h2 = the new height of the cylinder
SA = surface are of the cylinder
the radius and the height are shrunk down to a third of
their value therefore
r2 = r1/3
h2 = h1/3
SA = 2(PI)r^2 +
2(PI)rh
SA = 2(PI)[(r1^2)/9] +2(PI)(r1/3)(h1/3)
Simplifying
SA = [2(PI)r]/9 * (r1 + h1)
Answer:
12 milkshake can be made by 1/3 cup
1 milkshake can be made by (1/3)/12 cup
72 milkshake can be made by ((1/3)/12)*72 cup = 2cup
