What are the properties of a dodecahedron star?
The dodecahedron star has 30 edges, 12 faces, and 20 vertices. But, a 3D dodecagon star has 60 edges, 24 faces, and 40 vertices but i'm not sure. Some people still need help on how many edges faces and vertices a dodecagon star has. Thanks for your cooperation by looking at this answer.
Can you name a soild shape with no faces and no vertices?
No. Every solid shape has at least one face. The closest you will get is a sphere, which has no edges or vertices, but it still has a face.
Number of faces on a sphere?
A sphere is continuous with no edges, so a "face" doesn't really apply. It has a surface, and if you consider that a "face" then it has one. If you are looking inside and out, then two. If you do not consider a surface a face, then it has no faces. I am not sure how you would explain it with Euler's formula.. I am curious as how you would explain it in this manner. Euler's formula shows that e^ix traces out the unit circle in the complex number plane as x ranges through the real numbers. Not sure what this has to do with faces of a sphere... Euler characteristic perhaps? I am still not sure what this tells me about the number of faces that a sphere has. This basically proves the Euler Characteristic. You can map any polyhedron inside the sphere and get the same result. Are you implying that since any number of F can be mapped, that a sphere has infinite number of faces? That is pretty neat if that is the conclusion. So in regards to answering the question, you can use your method and explain it to your students. I think they can handle it if you do it properly. Something of the nature: Imagine a shape/polyhedron inside a sphere. Now map out or project the vertices's and edges of the polyhedron onto the sphere. It is like having the shadows of the edges and vertices's being mapped onto the wall of the sphere. The mapped image still has vertices's and edges and faces. They are the same amount of faces as the original polyhedron. Now imagine any polyhedron or shape inside the sphere. You can do the same with as many sided and faced shape as you want. Thinking this way you can view the sphere having infinite faces because you can map out any shape/polyhedron this way, no matter the number of faces. Then they will have this embedded into their memory and think that a sphere will have infinite faces. If they ever major in math and take topology... they will learn that a sphere has no faces.Hope this helps.
Is a right angle still a right angle if you turn it upside down?
Yes, the angle is still 90 degrees so it is still a right angle.
How many square inches in a 18 inch Dia. circle?
The formula for the area of a circle is A = PI R squared.Pi is about 3.1416R is the radius, half the diameter or 18/2 = 9A= 3.1416 * 9 * 9 = 254.4696 Using more digits in PI will give slightly different answers such as3.14159265359 * 9 * 9 = 254.469004941 which still is about the same value.So the area of an an 8 inch diameter circle (rounded) is about 254.5 square inches
How many edges vertices and edges does a rectangle2D have?
Edges: 4, Vertices: 4 and Edges: still 4, their number hasn't changed!
How do you know when a pavlova is cooked?
You'll know when the pavlova is cooked when it looks crisp at the edges which will have started to crack slightly. The top will be dry but if you press on the underside it'll give a little as the centre should be still a little squishy/soft..
Is there still slaves in the world?
Slightly.
Does the type of glass change the amount in the glass?
An eight ounce glass is still an eight ounce glass, no matter what type or style it is.
Is there a specific name for glass that is still tinted that glass-shade of green?
(deleted previous flaming harassment, still up for answering)
Why does the speed of light vary?
The speed of light varies because the absolute speed of light "C" is measured in a vacuum. When light travels through air, it goes slightly slower. When light travels through denser mediums still, such as glass, the speed decreases further still.
If a glass cup falls from the counter in shatters on the ground is it a physical change?
Yes. The glass is still glass.
Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
How much freon does a 2004 jeep grand Cherokee with 4.0 engine take?
If you look carefully under the hood you will find a sticker that will give you the poundage. Some systems still have what is called a "sight glass" that is usually located on top of the receiver dryer. what the sight glass does is let you know when the system is full. (when the system is slightly low you will see a white foam in the glass,when full no foam)
What does it mean when Someone calls you silly-stupid?
When someone calls you "silly-stupid," it could be a playful and affectionate way to tease you. However, it's important to consider the context and the tone of the person’s voice to understand the intention behind the words.
Is glassblowing to create sculptures out of glass a physical change?
it is a physical it changes shape but its still glass
When light passes OUT of glass what does it do?
Unless it`s colored glass, it will still shine its original color.
