Answer:
86in²
Step-by-step explanation:
Find the complete question attached
Area of the circle = πr²
Area of the square = L²
Length of the side of the square
r is the radius of the circle
r = L/2 = 20/2 =10in
Given
Length of the side of the circle = 20in
Area of the square = 20²
Area of the square = 400in²
Area of the circle =π(10)²
Area of the circle = 3.14(100)
Area of the circle= 314in²
Amount of plywood left over = 400in²-314in² = 86in²
 
        
             
        
        
        

so 4/5 of A is really 80% of A then.
since a whole A is 100% of A, 100% - 80% = 20%, A is being reduced by 20%, namely 1/5.
 
        
             
        
        
        
In 24 hours, the worm climbs 5 feet.
7-2= 5 (the worm falls 2 feet every night)
So,
5*8=40 
It will take bruce's worm about 8 days to get to the top of the well. 
I hope this helps!
