For parts ac what does the scale factor between two similar figures tell you about the given measurements a side lengths b perimeter c areas?
For a, it tells you how many times the side lengths grew or shrunk.For b, it tells you that the perimeter grows or shrinks: scale factor times original perimeter.For c, it tells you that the area grows or shrinks: scale factor squared times the original area.
What is the relationship between perimeters and areas of similar figures?
Whatever the ratio of perimeters of the similar figures, the areas will be in the ratios squared. Examples: * if the figures have perimeters in a ratio of 1:2, their areas will have a ratio of 1²:2² = 1:4. * If the figures have perimeters in a ratio of 2:3, their areas will have a ratio of 2²:3² = 4:9.
How do you find the scale factor of a cylinder?
how to do a scale factor of cylinder is that you find the base and the height and the length of A area hope you like my examples.
How do you find the scale factor from 9 square cm to 900 square cm?
The scale factor is 1:100 for the area. The linear scale factor is 1:10.
What happens to the area of a figure when the scale of the figure changes?
To find the new area, you have to multiply the original area by the square of the scale change. For example, you have a rectangle with adjacent sides of 3 and 4. Another rectangle has the same dimensions but with triple the scale. The original rectangle's area is 12. Multiply that by 9, which is the square of the new scale, and you get an area of 108. That matches up with the area of the new rectangle, which has adjacent sides of 12 and 9.
What are the relationship between the area scale factor and the side length scale factor of similar figures?
The area scale factor is the square of the side length scale factor.
What does the scale factor between two similar figures tell you about the given measurement perimeters?
Perimeter will scale by the same factor. Area of the new figure, however is the original figures area multiplied by the scale factor squared. .
What does scale factor of two similar figures tell you about area?
If the sides of two shapes have a scale factor of sf:1, then their areas will be in the ratio of sf2: 1.
How do you determine surface area of similar objects when it has a scale factor of 2?
For areas: Square the Scale Factor.
Rectangle with area of 144 and scale factor of 4 what is the area of a similar rectangle?
576
For parts ac what does the scale factor between two similar figures tell you about the given measurements a side lengths b perimeter c areas?
For a, it tells you how many times the side lengths grew or shrunk.For b, it tells you that the perimeter grows or shrinks: scale factor times original perimeter.For c, it tells you that the area grows or shrinks: scale factor squared times the original area.
What is the relationship between scale factor and area?
The area is directly proportional to the square of the scale factor. If the scale factor is 2, the area is 4-fold If the scale factor is 3, the area is 9-fold If the scale factor is 1000, the area is 1,000,000-fold
Suppose rectangle E has an area of 9 square centimeters and rectangle F had an area of 900 square centimeters The two rectangles are similar What is the scale factor from rectangle E to rectangle F?
100 is the scale factor
How does scale factor relate to area?
If the scale factor is r, then the new area will be the area of the original multiplied by r^2
How does the scale factor apply to the area?
The areas are related by the square of the scale factor.
How can you use scale factor to find a new perimeter and area?
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
Two similar triangles have a scale factor of 35 What is the ratio of their areas?
Their scale factor is 3 : 5, which mean their sides scale factor is 3 : 5, too. The area formula : S = bh/2 ---> The ratio of their areas : (3 : 5)^2=9 : 25 It's the answer.
