Math 42 Done-Probably hardest ever ||

[uzair shahid]

All of them are nearly wrong ..
Radius = 87 cm
speed = 1841 (smth like tht .. close)
n= 20

speed was 1744.
other 2 are correct

Yes but am sure n=20 nd radius is 87 cm because i reviewed them with my teacher after the exam.

HARD no way..the paper was easy... yeah i accept that the paper was tricky..but it was easy...and time consuming was too lengthy... i finished the whole paper leaving 20 marks within 1 hour and later on by giving deep concentration i did the other 20 marks i loved the paper and i m hoping for A* and by the way if the threshold is low like about 75-80% than i probably think many candidates ll be able to accomplish A* INSHAH ALLAH

Can You explain how you got 1744 as speed

speed=volume(cm^3)/time(min) then divide this answer by the area of cross section to get the speed in cm/min
