    i got 104cm^3 for the volume not sure i am correct tho!
    i did 750/120 = 6.25-a^2
    a=6.25
    a^3=15.625
    so 1600/15.625
    =102.4

    What did you guys get for the question about the parallel lines, how many spheres made. I ****ed up the sphere one and got 39 or something, but i did the correct working with the wrong numbers. I got 188 for the last one, I think thats right lost of others got that as well
    Like 1400 and something 😭 for the last one it was something like 188

    Yeah I think the volume was something like that. I don't remember what the angle was but I just used pythagoras to get the diagonal length of the plane, then sohcahtoa.
    What was q 19?
    q 19 is the circle angles and you x the angle in the primiter to get the center .

    what about the q 2 part b which the 4 pens for small box and 10 for large one

    was the formula t = 4x+10y ?

    Yeah I'm sure that was the formula. Was time for the acceleration/differentiation question 2 seconds?
    Don't remember the answer to q 19

    Yeah I got that, but I did it differently.
    I did 750/120 was 6.25.
    Then square root 6.25 to get 2.5
    Then x times 2.5^3 = 2000
    2000/2.5^3 = 102.4

    yes right i got that but the q asked for 1 decimal place so i did 24.1 right ?

    i didnt do the velocity one it was hard for me

    what about the graph q for the estimation i got 18 and for the second part 20 or the other way around i dont remeber what did you got ?

    Which graph question? Not the line equation prediction? Are you talking about the interquartile range?
