Circle groups to show 3x(2x3)
2 answers:
Answer:
This problem is asking for a graphic solution, which is attached.
We just need to make groups, first to express 2x3. we make two groups with three elements each, then, we graph three groups exactly equal.
At the end, we must have three groups and each of them must have two groups with three elements. If we count all elements, we will have 18.

<h3>Answer with explanation:</h3>
It is given that:
Circle 1 has center (−4, −7) and a radius of 12 cm.
Circle 2 has center (3, 4) and a radius of 15 cm.
Two circles are said to be similar if by some translation and dilation it could be placed over the other to form the same circle.
The circles are similar because the transformation rule ( x,y ) → (x+7,y+11) can be applied to Circle 1 and then dilate it using a scale factor of 5/4
( Since, as the center of circle 1 is (-4,-7)
so,
(-4+7,-7+11) → (3,4)
( Since, the radius of circle 1 is 12 and that of circle 2 is 15 cm.
so, let the scale factor be k .
that means :
