Answer:
Area of the truck tank is [tex]1356.48ft^2[/tex]
Step-by-step explanation:
It is given height of the cylinder h = 50 ft
Radius of cylinder is r = 4 ft
Surface area of the cylinder is equal to
[tex]A=2\pi rh+2\pi r^2[/tex]
Now putting the value of r and h
[tex]A=2\times 3.14\times 4\times 50+2\times 3.14\times 4^2[/tex]
[tex]=1356.48ft^2[/tex]
Therefore area of the truck tank is [tex]1356.48ft^2[/tex]
