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

Answer:

D 1054

Step-by-step explanation:

okay so you can handle most of it by getting the perimeter of the end and multiplying by the length.

( 14 + (2π7)/2 ) * 25

then you've just gotta add in the end pieces

π * 7^2
