Answer:
The area of hub cap is 452.16 square centimeters.
Step-by-step explanation:
We are given the following in the question:
Radius of hubcap = 12 cm
A hubcap is of the shape of circle.
Area of hubcap = Area of circle
Area of hubcap =

where r is the radius of the hubcap.
Putting the values, we get,

Thus, the area of hub cap is 452.16 square centimeters.

Step-by-step explanation:
I might not be completely right but I think so.
check the picture below.
so, those are the points, now, the line of symmetry, the red one, is the line that will cut the vertex is half and will be perpendicular to the opposite side.
now, the slope of the black line we can just get it off the grid, notice the rise and run, rise/run = 6/6 = 1.
now a perpendicular line to that one will have a negative reciprocal slope, thus

so the slope of that perpendicular line will be -1, so we're really looking for the equation of a line whose slope is -1 and runs through -6,3.
![\bf (\stackrel{x_1}{-6}~,~\stackrel{y_1}{3})\qquad \qquad \qquad slope = m\implies -1 \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-3=-1[x-(-6)] \\\\\\ y-3=-1(x+6)\implies y-3=-x-6\implies y=-x-3](https://tex.z-dn.net/?f=%20%5Cbf%20%28%5Cstackrel%7Bx_1%7D%7B-6%7D~%2C~%5Cstackrel%7By_1%7D%7B3%7D%29%5Cqquad%20%5Cqquad%20%5Cqquad%20%20slope%20%3D%20%20m%5Cimplies%20-1%20%5C%5C%5C%5C%5C%5C%20%5Cstackrel%7B%5Ctextit%7Bpoint-slope%20form%7D%7D%7By-%20y_1%3D%20m%28x-%20x_1%29%7D%5Cimplies%20y-3%3D-1%5Bx-%28-6%29%5D%20%5C%5C%5C%5C%5C%5C%20y-3%3D-1%28x%2B6%29%5Cimplies%20y-3%3D-x-6%5Cimplies%20y%3D-x-3%20)

Answer:
A negative exponent means that the number will be a decimal.
so 4 X 10^-9 (-9 being the exponent of 10)
the answer to this equation would be 0.000000004 because the decimal moves 9 times to the left
