Question

if a figure has 9 sides how many vertices and edges does it have

Answer 1

In general, if a figure has n sides, then it has n vertices and n edges.


So if a figure has 9 sides, then it has 9 vertices and 9 edges.

Answer 2

is it the same if the figure is a solid figure like a block type of figure i cant really explain it

Answer 3

For 3D figures, it's a bit different, but they can be found using the formula


V - E + F = 2


where V = number of vertices, E = number of edges, and F = number of faces


This of course only applies to polyhedra.

Answer 4

yes but on the page i am doin it doesnt show the fu=igure it just asks ''if the 2 bases have 9 sides how many vertices and edges does it have''

Answer 5

hmm not sure, one sec

Answer 6

thank you

Answer 7

does it refer to any other page or figure at all? how do you know it's referring to a solid figure?

Answer 8

its meaning a solid figure cause thats what the hwole lesson is about

Answer 9

ah ok that makes sense

Answer 10

would you perhaps be able to answer that for me?

Answer 11

are these two figures touching or adjacent at all? does it say?

Answer 12

my guess is that somehow there's more info being referenced thats missing somehow

Answer 13

im not forsure i will get the oage and copy the problem

Answer 14

alright, sounds good

Answer 15

april made a model of a prism whose bases have 9 sides each. How many vertices and how many edges did her model have?

Answer 16

ah a prism...thanks


There are 9 edges per base, so there are 2*9 = 18 edges


Add in the 9 lateral edges to get 18+9 = 27 edges total


------------------------------------------------


There are 9 vertices per base as well, so there are 2*9 = 18 vertices

Answer 17

thank you soooooo much!!! i ahve such a hard time with math and now it just got a whole lot easyierrrr

Answer 18

np, glad to be of help
