The formula for the total surface area of a cylinder is given by:
A = 2πr(r+h)
where A is the total surface area, r is the radius, and h is the height.
Plugging in the values, we get:
A = 2(3.14)(4)(4+15)
A = 2(3.14)(4)(19)
A = 2(3.14)(76)
A = 2(239.44)
A = 478.88
Since we're rounding to the nearest tenth, the total surface area of the cylinder is approximately 478.9 feet^2.
Therefore, the closest answer choice is 477.3 feet^2.
