Two rectangular prisms are similar the measures of two corresponding sides are 3cm and 5 cm what is the ratio of the surface areas of the prisms?
The length scale factor = 5/3 So the area scale factor is (5/3)2 = 25/9
What is the scale factor of 5 cm to 1 m?
1 : 20
How can you find the scale factor from a larger figure to the smaller figure using the scale factor from the smaller to larger figure?
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.
Erin has scanned a 4 by 5-inch postcard and she wants to reduce it to make a graphic for her website She will use a scale factor of 1 in equals 2 cm What will be the dimensions of the graphic?
8 cm x 10 cm
A vector that is 1 cm long represents a displacement of 5 km how many lilometers are represented by a 3 cm vector drawn to same scale?
if 1 cm is 5km.... 3cm? 5+5+5 ..15km dirrtyy suckas!
What is the scale factor for 5cm if the model is 58.7cm and actual is 140.9m?
the scale factor for a model is 5 cm + _________ m

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.
If a map had a scale factor of 2 cm to 5 miles what would that mean?
It means that every 2 cm on the map would represent 5 miles in the real world.
What is the scale factor if 5 centimeters equals 2 km?
5 cm = 0.05 m = 0.00005 km 2 km = 2000 m = 20000 cm
How do you find the scale factor?
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
How can you find the scale factor from a larger figure to the smaller figure using the scale factor from the smaller to larger figure?
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.
How do you find a scale factor from the smaller figure to the enlarged figure?
Look for corresponding parts of the two figures. Their ratio is the scale factor. For example, if you have two similar triangles, one has a side of length 3, and the corresponding side on the other triangle is 5, then the scale factor is 5/3 going from the small triangle to the big, or 3/5 going from the big triangle to the small.
In a scale of 1 to 40 000 how many centimeters on a map are represented by 2km on the ground?
You will see a distance of 5 cm on your map represent a 2 km distance across the landscape. Your 2 km is 2,000 meters, and there are 100 cm in a meter. That makes for 200,000 cm in 2 km. If you "reduce" or scale it down by a factor of 40,000, you'll get 200,000 / 40,000 = 5 cm.
