What is the ratio of the areas of an equilateral triangle and a circle if their perimeters are same?
It is 0.6046 : 1 (approx).
How do you calculate the relative error in areas of triangles?
by checking the edges
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 it true that when equilateral triangles have equal perimeters they must also have equal areas?
Yes.
What do you know about the perimeters of similar figures?
The areas are different.
What is the similarity ratio and the ratio of the perimeters of two regular octagons with areas of 18in2 and 50in2?
is it 3:5 and 3:5
What is the width of two similar rectangles are 45 yd and 35 yd what is the ratio of the perimeters of the areas?
The ratio of their perimeters is also 45/35 = 9/7. The ratio of their areas is (9/7)2 = 81/63
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.
If the area of triangle B is 64 times greater than the area of triangle A how much greater is the perimeter of triangle B?
IF triangles 'A' and 'B' are similar (they both have the same angles),then the perimeter of 'B' is 8 times the perimeter of 'A'.If they're not similar, then the ratio of areas doesn't tell you the ratioof perimeters.
How do changes in dimensions of similar geometric figures affect the perimeters and areas of the figure?
First you have to go on stop being a fat kid
Why would two shapes have equal areas and perimeters?
There is no particular reason. In fact, in general, two shapes will have different areas or perimeters or both.
If the similarity ratio of two similar octagons is 3 to 5 what is the ratio of the areas of the octagons?
9:25
Can a parallelogram and a rectangle have the same perimeters but different areas?
Yes.
How do their areas triangles compare?
I'll be happy to help you, but in order for me to compare the areas of those triangles, you have to tell me the areas of those triangles.
