Answer:

D looks to be the only good solution.

Step-by-step explanation:

19.8 is roughly 20

9.8 is roughly 10, so 1.1 represents 1.10 which is increased by 10%

5.1 is still around 5, & 1.05 is 1 increased by 5%

Very rough estimate will be given.

Hope this helps. :0)

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
