Answer:
Since your diameter is 8,
half of that is 4.
We are going to find the area now of both the bottom and the top.
4^4 = 16
16 x 3.14 = 50.24
Now we multiply by two since there are two circles (bottom and top) we only got one circle's area.
50.24 x 2 = 100.48
Now we need to find the round curved area.
In order to do that we need to find the circumference them multiply by the height:
2 x 3.14 x 4 = 25.12(circumference)
25.12 x 19Height) = 477.28
Now we need to add both the areas(surface area):
477.28 + 100.48 = 577.76 yard2 is your answer.
