Answer: 30%
Step-by-step explanation:
Percent error = 
Estimated number of games win this year = 7
Actual number of games won = 10
Now ,   the percent error of Doug’s estimate = 
Hence, the percent error of Doug’s estimate = 30%

Answer:
Therefore 200.96 ft.of fencing are needed to go around the pool path.
Step-by-step explanation:
Given, a circular swimming pool has a radius of 28ft. There is a path all the way around the pool. The width of the path 4 ft.
The radius of the outside edge the pool path is
= Radius of the pool + The width of the path
= (28+4) ft
= 32 ft.
To find the length of fencing, we need to find the circumference of outside the pool path.
Here r= 32 ft
The circumference of outside edge of the pool path 
= 
 

=200.96 ft.
Therefore 200.96 ft.of fencing are needed to go around the pool path.
 
        
             
        
        
        
I think the answer is 50" because if the table is 42" and it needs to hang over 8" then it would have to be 50"
