The solution of the function for π is 
Step-by-step explanation:
The equation πr² gives the area A of a circle with a radius r
To Solve the function for π
- Write the function
- Keep π in one side and all other terms in other side by using any operation you need (+ , - , × , ÷)
∵ A = πr²
- You need to take r² from the right hand side to the left hand
side to keep π in the right hand side alone
∵ r² is multiplied by π
∴ Divide both sides by r²
∴ 
∴ 
- Switch the two sides
∴ 
The solution of the function for π is

Answer: The width of the library is 22feet.
Perimeter = length+ length+ width+ width
The problem is telling us that the perimeter is 116 and the length is 36. So let’s plug it in and solve for width which equal w
w= width
Step 1: 116= 36+ 36+ w+w
Step 2: 116=72+ 2w
Step 3: 116= 72+2w
-72 -72
Step 4: 44=2w
Step 5: divide 2w on both sides ( 44 divided by 2)
Step 6: w= 22
