36 pie is half capacity..hence 72 pie is full.
hence 1/3*pie*r*r*h=72 hence here h will be 8 unit.& then r will be 3 unit.
in side ways for half capacity radius will be required height.

6.40 am ans
longitudinal difference=70W-10E=80
means destination is 80 degree West from start point
time difference=4min*longitudinal diff =4*80=320 min
for linear distance it reach at 2am+10 hr=12pm
but here 12pm - 320 min = 6.40 am

In 6 hours
[Hrs/capacity]=[8/1] , [7/(1/2)], [6/(1/4)], [5/(1/8)], [4/(1/16)], [3/(1/32)], [2/(1/64)], [1/(1/128)]

1!+2!+3!+ ......+50!
= 50!(1/50! + 2/50! + .....+ 1/50 + 1)
= 50!*1.02 (add last 2 or 3 terms , rest are too small)
= 51!/50
