The Surface area of the cylindrical tower is 5181 ft cube.
<h3>How to find surface area of a cylinder?</h3>
Surface area of cylinder = 2πr² + 2πrh
where
Therefore,
r = 30 / 2 = 15 ft
h = 40 ft
Surface area of cylinder = 2πr(r + h)
Surface area of cylinder = 30π(40 + 15)
Surface area of cylinder = 30π(55)
Surface area of cylinder = 1650π
Surface area of cylinder = 5181 ft³
