Answer:
24
Step-by-step explanation:
The area is calculated by multplying radius (half of diameter) by itself and then with number pi
the area for this circle is given as
144π m^2
144 is the squared form of 12 if the radius is 12 the diameter is 24
First you need to find the rule or 'equation' that this system goes by before we can solve what H' point is located.
So, to do so, label out the triangles points:
A(-7, 6), B(-5, 3), C(-1, 3) to A'(1, 4), B'(3, 1), C'(7, 1)
Now for A to A' which is -7 to 1 is a 8 point difference and A to A' which is 6 to 4 is a -2 point difference, indicating:
(x + 8, y - 2)
Now:
B(-5, 3) -> (-5 + 8, 3 - 2) = B'(3, 1)
C(-1, 3) -> (-1 + 8, 3 - 2) = C'(7, 1)
Now to simply solve for H to H':
We know H 's coordinates are: (-7, -5)
Now add in the rule and solve:
(-7 + 8, -5 - 2) = ?
Answer: (1, -7)
