What happens to the radius of a cone if a cone of say radius 8 cm is cut in half?

just do it regularly then divide the volume by four when you get the volume answer
=============================================================
The original cone is say, 3 cm high and has a radius of 8 cm. the formula is pi times the radius squared times the hight, so pi*64*3=192pi. the second formula is 3*4 squared times pi, so 48pi, which is one fourth of 192 pi.

What happens to the circumference of a circle when its radius is cut in half?
It splits
What is half of a cone?
it a cone cut in half from the top
How do you find the radius of a cone only knowing slant height?
If you cut the cone in half then drop a line from the point down to the centre of the base, you can then find the radius, which is the the base of one of the triangles you now have. You need to know one of the angles though, then work out the radius through trigonometry.
What happens to the volume of a cylinder if the radius and height are cut in half?
The volume becomes one eighth.
What fraction of the diameter is the radius?
The radius is basically the diameter cut right in half so the radius' fraction would be 1/2 of the diameter

If the radius of a circle is cut in half what happens to the area?
it is cut down by a factor of four since it is proportional to square of radius

What is a cone cut in half called?
It is called a frustrum
How do you find the radius of a sphere?
You have to cut the sphere in half and then measure across.

Can a triangle be obtained on the cross section of a cone?
Yes if cut in half from its apex to its base diameter.
What happens when you cut a tapeworm in half?

Why does a cylinder have one more plane of symmetry than a cone?
A cylinder and a cone have infinitely many planes of symmetry because of the circular face. However, a cylinder can also be cut in half lengthwise (imaging cutting a soda can in half), while a cone cannot (imagine cutting a ice cream cone in half). Therefore, a cylinder has one more plane of symmetry than a cone.
