Why is a circle different to a cone or cylinder?
Because a circle is a two-dimensional figure - the other two are three-dimensional. The circle is just a flat thing that is just drawn while both a cone and cylinder are 3D. The cone has a flat circle on the buttom and the rest is a triangle the is circlier, As shown: As A cyliner has to cirles , on the top and botom and the rest is a big 3d of it, as shown: While the circle is flat at of all of them, as shown:
How much volume of slump cone?
draw a slump cone . now imagine what the shape would be if u extend the sides of the slump cone. you'll have a complete cone with the base of 20 cm and the hight of 60 cm. all you need to do is to subtract the big cone form the top small cone. V=1/3(3.14*0.22*0.6) - 1/3(3.14*0.12*0.3) V= 0.02198 m3
Does a rectangular prism have an apex?
No. It has a flat top, no matter how you place it.
Is a cone a cylinder?
No, it is not. For a cone, think of a standard ice-cream cone shape (or a witches hat) - a circular top OR base (but not both), which has sides coming off that taper into a point. Whereas a cylinder has a circular top AND base, (like the shape of baked bean cans), with sides joining both top and base.
Why is a cone not a prism?
A cone has a curved surface and only has one base (the bottom). A prism however, has two bases (the top and bottom) and has only polygonal faces. A cone also has an apex which a prism doesn't.
