Scale factors are based on linear measures. The ratio of areas is the square of the rations of lengths. The ratio of the areas is 900/9 = 100, so the ratio of lengths is the square root of100 = 10.
The scale factor is 1:100 for the area. The linear scale factor is 1:10.
the scale factor for a model is 5 cm + _________ m
A scale factor tells how much the lengths in one diagram must be multiplied by to get the same lengths in a second.One diagram could be a map and the second the real world!To calculate the scale factor, measure the corresponding lengths in the same units and then divide the length of the second diagram by the length of the first diagram; this will give you the scale factor to convert the first diagram into the second diagram.For example, if you were to draw a map of you street, you may decide that 2 centimetres on the map will represent 1 metre in the real world.The ratio here is 2 cm : 1 m.However, 1 m = 100 cm which means that the ratio is 2 cm : 100 cmwhich is a scale factor of 100 cm ÷ 2 cm = 50.Another example: if you have two similar triangles and the corresponding sides measure as 5cm in the first triangle and 2 cm in the second, the scale factor is 2 cm ÷ 5 cm = 2/5 or 0.4
It is 2 cm : 100 m or 2 cm : to 10000 cm which is equivalent to 1 to 5000
The area of a square is calculated by squaring the length of one of its sides. In this case, the side length is 8 cm, so the area would be 8 cm x 8 cm = 64 square cm.
The scale factor is 1:100 for the area. The linear scale factor is 1:10.
A scale factor in a number that changes the size of a shape by that scale examples: 1: if you have a square that is 1cm by 1cm and you increaseit by a scale factor of 3 the square would then be 3cm by 3cm 2: if you had a 2cm by 2 cm square and increase by a scale factor of 0.5 you'd get a 1cm by 1 cm square
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
The scale factor is usually stated as a linear enlargement factor. Therefore, the area enlargement factor is the square of the scale factor, in this instance, 9. The area of the original drawing was thus 396/9 = 44 cm2.
the scale factor for a model is 5 cm + _________ m
900 cm = approximately one (0.968751938) square foot.
Area = 45*20 = 900 square cm
1/400
It is the same as 2 cm = 3 m or 1 cm = 1.5 m The scale ratio would therefore be 150:1
pi * r2 = 900 pi [cm2] so r2 = 900 So the radius is the square root of 900 = 30 cm
the answer is 80cm.
