The surface area of a cylinder can be calculated using the formula:
Surface Area = 2Ï€rh + 2Ï€r^2
Where:
r = radius = 4 feet
h = height = 3 feet
Surface Area = 2(3.14)(4)(3) + 2(3.14)(4)^2
Surface Area = 75.36 + 100.48
Surface Area = 175.84
Therefore, the surface area of the outside of the cylinder is approximately 175.8 square feet.
