The answer for this problem is z=18
Answer:
9^-4
Step-by-step explanation:
9^-6=?*9^-2
Let the unknown=x
9^-6=x*9^-2
9^-6=9^-2(x)
x=1/9^6÷1/9^2
=1/9^6×9^2/1
=9^2/9^6
x=1/9^4
x=9^-4
Check
9^-4*9^-2
=9^-4-2
=9^-6

Answer:
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
