You need 3 formulas for this problem.
area of rectangle = length × width
circumference =
[tex]2\pi \times r[/tex]
area of circle =
[tex]\pi \times {r}^{2} [/tex]
you use circumference to find length of rectangle so you can find the area of the rectangle and the add up th e area for the rectangle and both circles for surface area
[tex]2\pi \times 3 = 18.84[/tex]
[tex]18.84 \times 14 = 263.76[/tex]
[tex]\pi \times {3}^{2} = 28.26[/tex]
[tex]sa = 263.76 + 2(28.26) = 320.28 [/tex]
320.28 ÷ 3.14 = 102tt yd^2
