Afuel-tanker's tank is 50 feet long and has a diameter of seven feet. determine the surface area of the fuel tank.

1176.679ft²

Step-by-step explanation:

The question is on surface area of a cylindrical fuel tank

Equation for surface area of a cylinder

S.A = 2rh +2r²

where r is the radius of cylinder and h is height of cylinder

Diameter=7'⇒r=3.5' and h=50'

Surface Area= 2×3.142×3.5×50 + 2×3.142×3.5×3.5

S.A=1099.7+76.979=1176.679ft²

1176.5 square feet

Step-by-step explanation:

We are given that the length of a fuel tanker is 50 feet and its diameter is 7 feet and we are to find its surface area.

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

Surface area of cylinder =

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

Surface area of fuel tank = = 1176.5 square feet

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
