Answer:
D
Step-by-step explanation:
To get the total surface area, you need to find:
The area of the rectangle, the area of both semicircles and the curved area underneath.
[tex]TSA = lw + \pi r^{2} + \pi rh[/tex]
The area of two semicircles is just the same as the area of one circle.
The curved area is half of the curved area of cylinder, so we can just remove the 2.
[tex]TSA = (25)(14) + \pi (7)^2 + \pi (7)(25)[/tex]
[tex]TSA = 350 + 49\pi + 175\pi[/tex]
[tex]TSA = 224\pi + 350[/tex]
TSA ≈ 1054cm^2
