Area of circle = pi r^2    =    64 pi   

      subtract 1/2 (unshaded area) = 32 pi

         subtract area of triangle  1/2 b h = 1/2 16 8 = 64

(32 pi - 64) / (64 pi)

xf=xi+vit+1/2gt^2   put in the values you are given

xf = 1  +   vi t + 1/2 g t^2       ( I think that should be  MINUS 1/2 gt^2)

     anyway   xi is initial position = 1 m    (given)

I am a bit confused as to what you ae looking for?    You ask for xi    and then vi   and then xf    and you have a t = .01   (what is that?)

Your question is not well formatted/entered     v = 32 pi     or   .32 pi

                                                                          depth is 66   or  6   ft ?

Volume of a CONE = 1/3 pi r^2 h      V = 32 pi ft³      h = 66 ft    r = ?

                     32 pi   = 1/3  66  r²

                               ^{r = 2.14 ft                              perhaps that was 6 ft deep?    then r =  7 .1 ft}

Since the committee must include Mark

  there are 9 memebers left from which to choose 2 remaining committee members

    9 c 2 = 36 ways

2 3 5 7 11 13 17 19

there are   8 x 7/2 = 28 combos

here are some possibles   2 3 = 5

  2 5 = 7

 2 11 = 13

  2 17 = 19

I don't think there are any more.....can you find any more?    4 out of 28

Just look for the value of the graph where x = 3      crudely circled below:

Re-compute:    -2 (0)^2  + 4(0)  +16 = ...........

First one      you need  3/4 of the amounts listed            amount * 3/4

Second one     ingredients listed are for EIGHT pancakes.....you want TWELVE    

                               If you wanted SIXTEEN    you would DOUBLE the ingredients wouldn't you ?

                                     well if you want TWELVE   , you need to 1 1/2 times the ingredients   (because 1 1/2 * 8  = 12)

C'mon..... you put   x= 0 into the equation and got  0 ???
