Answer:
Step-by-step explanation:
For this case we must determine the inverse of the following function:
Step 1:
We would write
or
Step 2:
We clear x:
Step 3:
"x" and "y" are exchanged:
The inverse is:
We will need to find the area of the circle. We will use this formula:
A =
* radius^2
The question says we will use 3.14 for.
And we know radius is equal to 22.
A = 3.14 * 22^2
A = 3.14 * 484
A = 1519.76
Round to the nearest tenth.
A = 1519.8
So, the maximum area the sprinkler can water is <span>1519.8</span> ft squared.
