Answer 1

Answer:

301.593

Step-by-step explanation:

surface area of a cylinder = 2πrh + 2πr²

where: r = 4 km radius

           h = 8 km

plugin values into the formula

surface area of a cylinder = 2πrh + 2πr²

                                          = 2 π (4) 8  + 2 π (4)²

                                          = 201.062 + 100.531

                                          = 301.593 km²
