Is figure B a scale copy of figure A

Figure is not a scale copy of Figure

Step-by-step explanation:

If Figure is scale copy of Figure , then there must be a scalar quantity for all the sides of Figure to get to all corresponding sides of . This means that there is a number that if we multiply it to a side of Figure , it equals to a corresponding side of Figure and this number has to be the same for all the corresponding sides of Figure and .

To get this number, the scalar quantity, we just divide the length of a side of Figure by the length of the corresponding side of Figure .

We can see that the side with length in Figure corresponds to the side with length in Figure .

Let be that scalar quantity. Solving for .

Now we have the scalar quantity . Let's just see if that's consistent with the other corresponding sides.

The other side with length in Figure corresponds to the other side in Figure with length . That's consistent.

The other two sides of Figure have the same length, . So as their corresponding sides in Figure have the same length, .

Since it's not consistent Figure is not a scale copy of Figure .

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
