QUESTION KIA THA?

a polygon which fits in B ..i think !!

 

[syed1995]

is parrallelogram or kite is a polygon??

Well if you are being technical Yes, but they are not regular polygons, regular ones are triangle, square and all the ones with -gon at the end.

what about polygon in histograms !!??

 

[syed1995]

what about polygon in histograms !!??

The literal meaning of a polygon is any closed shaped figure. so if you are being technical then everything which is not a line or dot. is a polygon.

help somebody in these circle

 

[Hammad Siddiqi]

When u are young, work to learn not to earn.

actually this is part of a learning program... or maybe you consider yourself too young to try..

Question 3 a part ii

even i am not able to solve it.. lol

 

[syed1995]

help somebody in these circle

Is the answer 38 ?? if it is then I know how to solve it

help somebody in these circle

ain't the angles in the same segment ?

 

[syed1995]

ain't the angles in the same segment ?

on two different circles?

 

[beeloooo]

on two different circles?

well it seems so both the segments on the two cirlces seem equal

just a guess though !!

guesses aren't meant to be in maths YOU NEED TO PROVE everything .. these sick people!!!!

anyways .. i think its vertically opposite angles ...

regardless I used the next 2 parts answers to make 180 degrees on a line .. to get the answer which is 38. Brb in 2-3 hours .. confirm it by then please that its the right answer!

for part b (i) you simply have to use formula pie(r)^2 x h = volume

now insert values you knew pie(r)^2 x (h= 5cm+12mm) = 0.2

i did the same. nd its not 5cm +12mm cz they said only the wick INSIDE the candle. so its only 5 cm. but in both ways answer does not match the mark scheme

it is said to b 1 rotational order of symmetry wen a fig hz turned full 360 degress nd return to its original position. but then if this is so, then even kite nd isosceles triangle nd isosceles trapezium will hv 1 rotational order of symmetry???

q.5 last part !! i don't know how to calculate the width and height of the bar pls if anyone can explain it plz ? :O

Yes. that's what i was arguing about last night with a couple of guys, when they say no rotational symmetry it basically means it only has the one rotational symmetry which every shape has.
