[Mayedah]

explain why

FC = FE+ ED+ DC
so -q + 2p -r ( because u can see r is parallel to DC but in opposite direction !

which one it asks four? do u want all

dont get u Q7 Part A ii)B

 

[AlphaBeta]

FC = FE+ ED+ DC
so -q + 2p -r ( because u can see r is parallel to DC but in opposite direction !

why is r opposite confused

explain why

well AF // CD so CD=r do FC=2p-q-r as Mayedah correctly stated

 

[Mayedah]

why is r opposite confused

R is parallel so it will have the same direction but u have to take it in - because ur going in the opposite direction !

 

[AlphaBeta]

R is parallel so it will have the same direction but u have to take it in - because ur going in the opposite direction !

got it jazakallah

is my answer correct

 

[kitecrystal]

ratio of square of both radius gives ratio of area of large circle to area of small circle...
area of 1 small circle is one tenth of area of large circle(since 5 circles are occupying half the area of large cirlce)
hence the ratio is 10:1
