<em>What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.</em>
Formulas:
area of a square: A = bh
area of a circle: A =

square measurements:
b = 28
h = 28
circle measurements:

(≈3.14)
r = 14
A = (28)(28)
A = 784
area of square = 784 in^2
A = 3.14 (

)
A = 3.14 (196)
A = 615.44 in^2
784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.
Answer:
By plus 2 points
Step-by-step explanation:
The median average is the midpoint in a list of acceding values, in this case the median is 16,18,<em>20</em>,24,28 so its 20. But after they score 30 points in their next game, the median will be 16,18,<em>20</em>,<em>24</em>,28,30. Since there is 2 midpoints we have to take the mean average of both, which is just adding up the value of all terms and then dividing by the number of terms in the list.
(20+24)/2 = 22
Our median average before the sixth game is 20 and after its 22, do the change in median is +2
