MATHS PAPER 22 / JUNE 2012?

[Rimi]

(300/360)pi(15)^2
15 was the radius ryt?

you had to add the triangle area too using the sin wala area wala formula :l it was area of the segment, not the major arc! And anwyay, it carried 4 marks

 

[snowbrood]

wat was da area f da major segment ....!!

 

[Rimi]

wat was da area f da major segment ....!!

686 i think.

 

[snowbrood]

i also added da area f da major segment n da triangle

 

[Rimi]

i also added da area f da major segment n da triangle

yeah you had to

 

[snowbrood]

r u cnfrm

 

[Rimi]

r u cnfrm

no xD but i think so.

 

[Fallen316]

the triangle was equilateral so i used the 1/2*b*h .
got 686.5

 

[Rimi]

the triangle was equilateral so i used the 1/2*b*h .
got 686.5

yeah i got that too what was the answer to the last vector part?

 

[snowbrood]

2 ratio 3

 

[Rimi]

2 ratio 3

the one below that?

 

[machiyara]

In Q8 area of segment were we supposed to take pie as 3?
I didn't do it, how many marks will I loose?

I used Sin Rule instead to get triangle's area.

1/2*15*15*sin60 .. correct right?

It was specifically mentioned in the question to take pie as 3 i think .. if it was really mentioned .. 1 mark from every part where you used pie.

I dont think the question asked us to take pie as 3!!

 

[snowbrood]

[walid bin khalid]

im pretty sure question 8 didnt ask us to take pie as 3!!

 

[nightmaressana]

im pretty sure question 8 didnt ask us to take pie as 3!!

Yesh, cause it didnt.... last question asked us to take pi as 3...
