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

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
