The formula for the surface area of a cylinder is:

Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):

Simplify:

Subtract 1413 to both sides:

Divide 94.2 to both sides:

So the height is approximately 45 millimeters.
T - 7 < 10, T = 28

Answer:
Palanzio's Pizza: Y= .90x+6.80
Giudo's Pizza: Y= .65x+7.30
.90x + 6.80= .65x + 7.30
.25x + 6.80= 7.30
.25x = .50
x = 2
