What happens to the area of a pentagon if the sides are doubled?
The ratio of areas is the square of the ratio of lengths. Ratio lengths = 1 : 2 → ratio areas = 1² : 2² = 1 : 4 → if the lengths are doubled, the areas of quadrupled (multiplied by 4).
What is the ratio of Two triangles that are similar and have a ratio of similarity of 310 what is the ratio of their areas?
If the ratio of similarity is 310, then the ratio of their area is 96100.
The ratio of the corrresponding edge lengths of two similar soilds is 4 5 what is the ratio of their surface areas?
The ratio of their surface areas is 42 to 52 or 16 to 25
How do you find the similarity ratios of two regular octagons with areas of 18 inches and 50 inches?
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
The ratio of the lengths of corresponding parts in two similar solids is 41 What is the ratio of their surface areas?
Area = length x length Therefore the ratio of areas of two similar objects is the square of the ratio of lengths. Lengths - 1 : 41 Areas - 12 : 412 = 1 : 1681
What is the ratio of Two similar trapezoids that have areas of 49cm2 and 9 cm2 find their similarity ratio?
7:3
How do you find the ratio between two circles when the diameters are given?
If you mean ratio then I don't quite understand the question.. but if you mean RADIUS Then you take the diameter and divide it by two. ============================================== There's no such thing as the ratio of circles. You can find the ratio of their diameters, the ratio of their radiussesses, and the ratio of their areas. -- The ratio of their diameters is: One diameter divided by the other one. -- The ratio of their radiusses is the same number as the ratio of their diameters. -- The ratio of their areas is the square of that same number.
How do you find the ratio of two areas?
In order to find the ratio of two areas, you times it by the number of a number to get the number of the numbers numbers number, and that number divide by the first number which is 6 and then do the square root of the numbers number to get that number, which you will times by 2.
The ratio of the lengths of corresponding parts in two similar solids is 4 1 what is the ratio of their surface areas-?
The ratio of their surface areas is the square of the ratio of the lengths. Since the ratio of the lengths is 4-1, then the ratio of the surface areas is 4^2-1^2 or 16-1.
What happens to the area of a pentagon if the sides are doubled?
The ratio of areas is the square of the ratio of lengths. Ratio lengths = 1 : 2 → ratio areas = 1² : 2² = 1 : 4 → if the lengths are doubled, the areas of quadrupled (multiplied by 4).
Two triangles are similar and have a ratio of similarity of 3 1 What is the ratio of their perimeters and the ratio of their areas?
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
The diameter of the moon is approximately one fourth of the diameter of the earth find the ratio of their surface areas?
Since the scale factor of the moon to the earth is 1:4, then the ratio of their areas will be the scale factor squared or 1:16. The ratio of their volumes will be the scale factor cubed or 1:64.
There are two rectangles what are the ratio of the first to the second?
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.
The two solids below are similar and the ratio between the lengths of their edges is 35. What is the ratio of their surface areas?
If the lengths are in the ratio 3:5, then the surface areas are in the ratio 9:25.
What is the ratio of Two triangles that are similar and have a ratio of similarity of 310 what is the ratio of their areas?
If the ratio of similarity is 310, then the ratio of their area is 96100.
Is the ratio of output force to input force of a hydraulic press equal to the ratio of the output and input piston areas?
Areas
The ratio of the corrresponding edge lengths of two similar soilds is 4 5 what is the ratio of their surface areas?
The ratio of their surface areas is 42 to 52 or 16 to 25
