Answer:
A
Step-by-step explanation:
first lets find the area of the square
A=l*w
12*12=144 m^2
then lets find the are of the circle
A=pi*r^2
A=3.14*(d/2)^2
the diameter of the circle is 12m
A=3.14*(12/2)^2
A=3.14*(6)^2
A=3.14*36
A=113.04 m^2
Now, lets subtract the area of the circle form the area of the square
144-113.04= 30.96 m^2
So, the answer is A
Answer:
9
inches
or
12.728 inches
Step-by-step explanation:
Use Phytagorean Theorem
Since both all sides of a square are equal, this means that 
and 
are equal.
So that leaves us with:
Simplify
Divide both sides by 2
Simplify
Find the square root of both sides
a = 9
(or if you want the decimal, rounded to the 3rd decimal place: 12.728)
