It works that way
As far the lenghts are same and it is also inscrbed in same circle the polygon is same,

Mitocyan:
This is unacceptable, how can you just rearrange the configurations of the sides of the octagon!!!!

LAST SHAPE FOR TODAY

Find the area of the polygon,
Or tell us the regularity your observe.

If you have any objection or questions to my workings you can please express yourself let's clear the doubt.

RTSC:
We have to draw the diagonals from each of the vertices so as to form some triangles.

Finding the areas of the different triangles and summing them up gives the area of the irregular polygon.

Here is the workings sir.

Workings here,
Look forward to my next shape.
I remain Mr shape.

Martinez39:
@ifada123
A = (3√(17+12√2))+(2√(22+12√2) = 29.9705627 (7 d.p.)

You are very correct but show your sketch or your complete analysis.
Meanwhile let me show my perspective too

Martinez39:
@ifada123
A = (3√(17+12√2))+(2√(22+12√2) = 29.9705627 (7 d.p.)

You are very correct but show your sketch or your complete analysis.

Anyone?

Bukswag:
I really would like to learn shapes. Though I'm not really solid at maths.

Please suggest PDF or websites

PDF will not teach you shape, not even all maths teachers can boost of Shape, shape is for does that can see and draw connections or relationship in things that are not obvious,
The best way to learn shape is practice,
Try and see the connection between already SOLVED shapes and the questions, ask questions on were you are not clear and know basic formula

Any one ?

Hatima:
Octagon

Smile
Since you know the name can you please solve its area for us?

RTSC:
We have to draw the diagonals from each of the vertices so as to form some triangles.

Finding the areas of the different triangles and summing them up gives the area of the irregular polygon.

OK sir try it out and give us the workings

Anyone?

Solid foods belongs to matured people, at this time everyone know what eight sided polygon is called, but what, how do we interact with an irregular polygon I believe it is a problem to many,
Show your workings
What is the area of the eight sided polygon?

dejt4u:
answer is 3.0502cm²


radius of the small circle is 0.8579cm

You are very correct
Show workings so that others can learn

Dear fellow lovers of shape,
I am having difficulty posting shapes with this account
Thus I open a new account @mrshape
You can follow me on this account to continue getting your regular shape
Thanks
@ifada123

castrol180:
Any mathematics teacher here should help solve this:

Florence spent 3/7 of her money on books, 1/4 of the money on clothes and 1/8 of it on her family. She then had #22.00 left. How much money did she have before this expenditure?

Maths is not ment for only mathematics teachers
(1-3/7-1/4-1/×Total=22
find their LCD
((56-24-14-7)/56)×Total=22
11/56 xTotal=22
Cross mutiply
11Total=22×56
Divide both sides by the coefficient of total
11total/11=22×56/11
Total=2×56
Total=#112.00

Any solution?

.

Find the area of the blue region

If you have been following my shape you should be able to solve this

Have they released any results ?

Martinez39:
Bring those shapes.

The system is not allowing me oo,
But will keep trying

Is like niaraland is preventing me from posting shapes,
System always overwhelmed,

The knowledge we get from electrical engineering is very practical, the problem is that you can't see materials to work with in making designs that will make you innovative as those in the western world (I made a foot detector foot match immediately I graduated, it was not pleasing to the yes,no material to work with no machinery for finishing),
In engineering you are supposed to be taught the basic principles and you as an engineer will think on what to invent with it,
Engineering is not meant to copy, as an average Nigerian engineer want it to be,
They prefer you teach then how the I iPhone X max was design and let them make it, rather than learn how telephone, integrated circutry, displays, cells,and design, allong with order basic needed knowledge,
That was why one richdad ask me to go and make robot rather than learning about circle, when the robot become faulty I will be lost in the ocean.
I don't see Nigeria improving in technology soon.
Why
(1) the supposed theorem we don't even understand it in in-depth
(2) that is the way the lecturer were taught.
(3) for the few engineer that understand it they don't have materials to implement it

starstaz:
I need learn learn as well.

Check my solution or mathenez's Above

Martinez39:


P = 6( 3tan(53°) + sec(53°) + 1) ≈ 39.8566476 units

You are very correct sir.
Let others bring their methods too

Let's imagine this is the time Jesus is coming(although no one knows the time),
Let's see who can interpret it.

SHOW YOUR WORKINGS,

Keep your answers coming
I need as many methods and approaches as possible

Find the perimeter of the figure

Darivie04:
You don't need in depth knowledge of a circle to build a robot naw

We are not doing in depth knowledge of maths here, this is basic secondary school maths and you even need more than this to design a robot,
I don't mean to assemble robot,
Go check on what brings about upward and downward movement in mechanical device

Any attempt?
