A fuel-tanker's tank is feet long and has a diameter of seven feet. Determine the surface area of the fuel tank.

1176.5 square feet

Step-by-step explanation-

Since fuel tank is a cylinder so we need to find the surface area of this cylinder.

Surface area of cylinder = 2. π. r. 2. +. 2. π.

Substituting the given values (h = 50, r = 7/2 = 3.5) in the above formula:

Surface area of fuel tank = 1176.5 square feet
