<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:
0.06
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
< means open circles
x-21<3 x≥21
-x+21<3 x<21
18<x<21 and 21≤x24
so the union of will be 18<x<24
