\pi (3)(7)+\pi (3)^2

Pi is 3.14 for our purposes

\pi (3)(7)+\pi (3)^2\\3.14(3)(7)+3.14(3)^2

Then solve

21(3.14)+9(3.14)\\\\94.2m^2

The truck's tank is a stainless steel cylinder. Find the surface area of the tank. Round your answer to the nearest hundredth.
Feliz [49]

Answer:

Area of the truck tank is 1356.48ft^2

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

A=2\pi rh+2\pi r^2

Now putting the value of r and h

A=2\times 3.14\times  4\times 50+2\times 3.14\times  4^2

=1356.48ft^2

Therefore area of the truck tank is 1356.48ft^2
