If you unroll the fence, you find it has a length equal to the circumference of a circle of radius 10 m and an average height of 3 m. Its two-sided area will be
... A = 2·(3 m)·(2π·(10 m)) = 120π m²
Then the amount of paint required is
... (120π m²) × (1L)/(100 m²) = 1.2π L ≈ 3.77 L
Got this from a website, hope it helps!
Answer: 
Step-by-step explanation:
The exponential function h, represented in the table, can be written as 
From table, at x=0, h(x) =10
Put theses values in equation,, we get

Also, for x= 1 , h(x) = 4, so put these values and a=10 in the equation , we get

Put value of a and b in the equation ,
→ Required equation.
