Answer:
Im not 100% sure but i know 2 and 4 are correct, the rest I think are all wrong but im not sure sorry
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

Step-by-step explanation:
First we need to get the slope of the perpendicular line
The slope of a perpendicular line is equal to the negative inverse of the slope of the given line
y

Now that we have the slope, we need to find the y-intercept.
To find the y-intercept, we need to plug-in values of
x
and
y
that the line passes through

Answer:
3
Step-by-step explanation:
15 minus 9 equals 6. 6 divided by 2 equals 3.
Angle POQ and Angle UOT are identical. This also applies to angles QOP and TOU, as they are the same angles as listed before.
