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
If 3 under is -3 than 3 over would be positive 3
We can rearrange the initial equation to y=mx+b
y=2x-5
Since perpendicular slopes must equal -1,
x=the perpendicular slope
2x=-1
x=-1/2
(Or you can just take the negative reciprocal above is just the "formula form" for it)
Therefore, the perpendicular slope is -1/2
