The Surface area of the cylindrical tower is 5181 ft cube.

How to find surface area of a cylinder?

Surface area of cylinder = 2πr² + 2πrh

where

  • r = radius
  • h = height

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
