You can't even find a calculator to buy. Bought one yet? Lol!

YUP!

 

[***amd***]

Any more information regarding the question? Don't give any hints btw.

yes

Is BC equal to AD or not?

it is. i just forgot to read the Q thoroghly (and i did the same durig the exam .-.)

 

[Asad.Babur]

Hight must be given

 

[Asad.Babur]

yes

it is. i just forgot to read the Q thoroghly (and i did the same durig the exam .-.)

Where is Hieght?

 

[funky brat]

solve my question instead of posting such kach

Are you asking from w09 paper 2?

 

[Dark Destination]

Amd. Is there any information missing?
What is the starting statement of the question?

Are you asking from w09 paper 2?

yup

 

[***amd***]

Where is Hieght?

uve to calculate it.

 

[Asad.Babur]

yup

Question No?

 

[Asad.Babur]

uve to calculate it.

[Asad.Babur]

GOT IT!

 

[funky brat]

yup

12-7=5
Then apply pythagoras.
QS^2= 14^2+ 5^2
QS^2= 221.

calculate:-

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

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

is part a 13?

is part a 13?

I havent even started solving it yet
be confident, u may be right dude.

don't you already know the answers?

 

[Asad.Babur]

(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

 

[Asad.Babur]

***amd*** you hurt me ?

 

[Dark Destination]

***amd***

a) BC= 13.9 cm
b) h=13 cm
c) Area of shaded= 36cm^2

Lol, is this right?

 

[Asad.Babur]

It took 15 mins to solve this heck!
