can anyone help me with q.5 part b plz ??

To find arc BC apply the formula 60/360*2*pie*(12); 12 is the radius of arc BC. you'll get 4pie. and for the ii part. find the arc AED by applying the formula for circumference of circle which is 2pie(r). since it's semicircle so we'll divide by 2 and arc length will be 3pie as the radius of arc AED is 3. so 3pie/4pie= 3/4.

can anyone help me with q.5 part b plz ??

we will use the perimeter formula. since it is a sector, we will form an equation like this:
2π(12) x (60/360) = nπ
now we can solve this equation

paper was awsum!!!!
wat u wrote for the two fractions having a value of 0.4

i wrote 4/10 and 2/5

(ii) b)

FC =FE + ED + DC
-EF + ED -CD (Opposite sides)
FC=-q +2p -r

c)
AY = 3/4 2p
AY = 3/2p = 1.5p
=FA + AY
-AF +AY
-r +1.5p
AY =1.5p -r

d)

YX=YB + BC + CX
YB - CB + 1/2CD
YX = 0.5p - q + 0.5r

are the answers correct .. If they are I would like to thank you .. because this will be the first time in my life that I have done a vector question correct

i wrote 4/10 and 2/5

same as me ? what a coincidence I wrote the same!

hahah i guess every body will b sharing this answer

 

[khizer shahab]

same as me ? what a coincidence I wrote the same!

oh oh oh yeh answer they i wrote 4/10 and 0.4/1 !!!is that correct !!

 

[syed1995]

oh oh oh yeh answer they i wrote 4/10 and 0.4/1 !!!is that correct !!

dosray ka pta nai .. pahla sahi hai .. /1 technically fraction nahi count hota .. but logic achi lagayi tum nay udher /1 haha

 

[Vogue]

oh oh oh yeh answer they i wrote 4/10 and 0.4/1 !!!is that correct !!

no i dunt think its correct cz 0.4 cant b written as 0.4/1 as far as i no. they askd for equivalent fractions.

calm down calm down ..I was just kidding i too wrote 2/5

 

[syed1995]

LOL

how could you help ... maths p1 is now pastpaper !!

 

[Vogue]

help meaning clear ur misunderstanding abt the question. u may find equi fractions in ppr 2 or in a levels?

Tomorrow's Paper is going to be tough, that's the feeling which I am getting, that's also what our maths teacher said, that tomorrow's paper is going to be tricky...
