Answer:
36.1 in²
Step-by-step explanation:
The total surface area of a cylinder of height h and radius r is given by ...
SA = 2πr² + 2πrh = 2πr(r+h)
For a cylinder of height 11 inches and radius 3 inches, the surface area is ...
SA = 2π(3 in)(3 in +11 in) = 84π in² ≈ 263.9 in²
Then the "extra" wrap area is ...
300 in² -263.9 in² = 36.1 in²
