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

1176.5 square feet

Step-by-step explanation:

Let us recall from the following question,

Because fuel tank is a cylinder, the first step to take is get the surface area of this cylinder.

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

Then,

The given values (h = 50, r = 7/2 = 3.5) as applied from the formula given,

The area Surface a of fuel tank = 1176.5 square feet
