4x divide 16 3x-4y it is the answer
V=hpir^2
d/2=r
so, at first, diameter is 48ft
48/2=24ft is radius
height is 25ft
so volume=25pi24^2 or 14400pi cubic feet
max of 9ft
if we want 9ft height
find r
hmm
14400pi=9pir^2
divide both sides by 9pi
1600=r^2
sqrt both sides
40=r
2r=d
2(40)=80=d
the new diameter is 80ft
N = 10*27 / 87 = 270/18 = 15
