The surface area of the cylinder is given by the formula:
A = 2Ï€rh + 2Ï€r^2
Where:
A = surface area of the cylinder
r = radius of the cylinder
h = height of the cylinder
Substituting the given values:
A = 2(3.14)(4)(3) + 2(3.14)(4)^2
A = 75.36 + 100.48
A ≈ 175.84
Therefore, the surface area of the cylinder is approximately 175.8 square feet.
