You need information about a pre-image AND and image to work out a scale factor.
how do you find the scale factor of two circles
The two scale factors are reciprocals of one another.
The scale factor is the ratio of any side of the image and the corresponding side of the original figure.
all you have to do is have to figure out from which of the shapes your starting with. So if you decide to start with a scale factor from the larger figure to the smaller figure all u do is the opposite. You do the small divided my the large. So if u want it from the small shape to the large shape scale factor you do the large divided by the small.
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?
1.25
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.
well.... first off you have to find the scale factor...
A scale Factor is Algbrea so you have to... x - + and/or divided.
You find the scale factor on a triangle by dividing the short side by the long side.
The linear scale factor is 100.
The remaining figure is the are of polygons that bounded by three dimensional figure .
