Answer:
See below.
Step-by-step explanation:
The figure is a cone. The formula for the volume of a cone is:

The radius is 4.8 and the height is 2.9. Substitute:

Use a calculator:

And we're done!
Polyhedron, by definition, is formed by intersecting planes, so each part of its surface is either a vertex or an edge, or a flat piece of a plane.
Explanation:
The definition of polyhedron implies that each side is a piece of a flat surface.
A: Yes, the sum of two sides are greater than the third side.
B: Yes, the sum of two sides are greater than the third side. (Would be an equiilateral triangl.)
C: No, the sum of two sides are less than the third side.
In general, To determine if 3 side lengths are a triangle, use the triangle inequality theorem, which states that the sum of 2 sides of a triangle must be greater than the third side. Therefore, all you have to do is add together each combination of 2 sides to see if it's greater than the third side.
Answer:
k = 0.167
Step-by-step explanation:
This is a direct proportion. That is as the number of chairs increases, so does the number of minutes needed.
y=number of chairs
x = time in minutes.
y = k x
4 = k * 24 Divide by 24
4/24 = k
You could leave it that way.
or you could do the division
k = 1/6 = 0.167
y = 0.167 x
