9:25
7:3
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
The ratio is 19/9.
If the lengths are in the ratio 3:5, then the surface areas are in the ratio 9:25.
The ratio of area is 4 : 81.
is it 3:5 and 3:5
If the ratio of similarity is 310, then the ratio of their area is 96100.
7:3
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
The ratio of areas is 18:50 which simplifies to 9:25 or 9/25 So the ratio of their sides is sqrt(9/25) = sqrt(9)/sqrt(25) = 3/5 That is, the linear ratio is 3:5
Measure any two corresponding edges. The ratio of these edges is the similarity ratio.
The similarity ratio of two circles can be determined by the ratio of their areas. Given the areas of the circles are 2π m² and 200π m², the ratio of the areas is ( \frac{2\pi}{200\pi} = \frac{2}{200} = \frac{1}{100} ). The similarity ratio, which is the square root of the area ratio, is therefore ( \sqrt{\frac{1}{100}} = \frac{1}{10} ). Thus, the similarity ratio of the two circles is ( 1:10 ).
For two similar polygons, the ratio of their areas is equal to the square of the ratio of their corresponding side lengths. Given the similarity ratio of the smaller polygon to the larger polygon is 2:3, we calculate the area ratio as follows: ( \left(\frac{2}{3}\right)^2 = \frac{4}{9} ). Therefore, the ratio of the areas of the smaller polygon to the larger polygon is 4:9.
3:1
I guess you mean the ratio of the areas; it depends if the 2 rectangles are "similar figures"; that is their matching sides are in the same ratio. If they are similar then the ratio of their areas is the square of the ratio of the sides.
If the ratio of the lengths of corresponding parts in two similar solids is 51, then the ratio of their surface areas is the square of the ratio of their lengths. Therefore, the ratio of their surface areas is ( 51^2 = 2601 ).
The similarity ratio is 1:4.
