-_- i m still not doing that Q.
teaching somebody. i need to concentrate. try to understand plz. no alerts

Let me SEE!

Bye Guyz, gotta sleep.. I hope I am correct by morning!

 

[***amd***]

Asad.Babur, say @@yesha to slap you thrice from my side ok?

LOLX! She's sleeping! cant do my majesty

Bye, This time seriosly!

(i) lets divide it in three parts, Square which is 8 in base and 13 in height (Diameter of Circle, Calculated by adding Base + Top / 2), and two equal triangles...
Triangle Base^2 + Hieght^2 = Hypotenuse^2
so 5^2 + 13^2 = 194

Sqaure root 194 and you get BC and AD = 13.928

(ii)Hieght = 13, as shows above

(iii) Volume of Trapezuim = (18+8)*13/2 = 169 (- Volume of Circle = 6.5^2 x Pi = 132.73) = 36.3 Round to 3 s.f

How did you get the diameter of the circle with that formula?

I didn't use it.
I don't even understand what i did myself. Can't think of it anymore :/
But somehow i got 13 I think i'm wrong.

whats that? what did u do to find the diameter in (i)?
I am feeling ur answer is wrong.

I am feeling ur answer is wrong.

Then whats the solution?

 

[***amd***]

Then whats the solution?

I am not a maths God!
i m still finding it out

 

[***amd***]

Asad.Babur ur solution is wrong

calculate:-

AD = BC
i) length of BC.
ii) hieght of trapezium.
iii) total area of shaded region, nearest to cm^2.

Awesome12
funky brat
all the maths freaks
try doing this the Q neither my class fellows, nor my add maths teacher could solve (though he did it after 20 mins )
but my Maths teacher, obviously, did

0.5 AB = BE
0.5 CD = CE
both because tangents of a circle are equal from the point of intersection to the points where they touch the circle

so BE + CE = BC = 9 + 4 = 13
and Asad.Babur, u got 13.9something

Owh Yeah!!!!!!!!!!!!!!!!!!!
Dark Destination , who is MATHs MASTER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[***amd***]

^^ though my brother told me the solution
I be shokha for no reason I am no Maths Master, i should die.

I am noway maatee, but my ans is not wrong I believe... Because hypotenues = base ^ 2 + hieght ^2 .....


Secondly, you asked your bro?

 

[Asad.Babur]

***amd***, this makes sense
