259.05 ft²

Step-by-step explanation:

Surface area of a cylinder =  

(where r is the radius and h is the height)

Given:

Surface area of one fence post = (2 × 3.14 × (1/2)²) + (2 × 3.14 × 1/2 × 7)

                                                    = 1.57 + 21.98

                                                    = 23.55 ft²

Therefore, surface area of 11 fence posts = 11 × 23.55

                                                                    = 259.05 ft²
