100\sqrt{3} is how long the shadow would be.

To solve, remember the ratio for a 30/60/90 triangle:
short side = x
long side = x\sqrt{3}
hypotenuse = 2x

the short side is the building, which is 100, so the long side is 100\sqrt{3}

Find the area of the circle then, multiply that by the height of the cylinder.

Area of a circle = PI x r^2

Area = PI x 8^2 = 64PI

Volume = 64PI x 11 = 704PI in^3
