Answer: The height is roughly 9 yards
------------------------------------
Explanation:
We'll use this formula
S = 2*pi*r^2 + 2*pi*r*h
which is the surface area of a cylinder
We're given
S = 2775.76
r = 17
The unknown is the height h, which we'll solve for
We'll use the approximation pi = 3.14
S = 2*pi*r^2 + 2*pi*r*h
2775.76 = 2*3.14*17^2 + 2*3.14*17*h
2775.76 = 1814.92 + 106.76*h
1814.92 + 106.76*h = 2775.76
106.76*h = 2775.76 - 1814.92
106.76*h = 960.84
h = 960.84/106.76
h = 9
