Answer:

Step-by-step explanation:
Given



Required
Determine the coordinates of B'
Since A' is the image of A; we need to first calculate the scale factor using

Make Scale Factor the subject

Substitute values for A' and A

Factorize the numerator



The coordinates of B' is then calculated as follows:

Substitute values for B and Scale Factor


Let
C---------> the circumference of a circle
D---------> diameter of a circle
r----------> radius of a circle
we know that
C=2*pi*r
D=2*r
so
C=D*pi-------------> pi=C/D
<span>Pi is defined as the ratio of the circumference of a circle to the diameter of that Circle
when you multiply the diameter in both numerator and denominator
pi*D=(C/D)*D------> pi*D=C
and the diameter is two times the radius
so
D=2*r
C=pi*D------> C=pi*(2*r)-----> C=2*pi*r
therefore
the answer is the option D
</span>Two times r equals the diameter of the circle. Pi equals the circumference divided by the diameter. When you multiply, the diameter is in both the numerator and the denominator, which cancels out, leaving the circumference
It would be H. hope this helps
