Answer:
x - 2y - 5= 0
i think is the answer for number 1 i hope it is
In order to solve this using V= B(h) (The B is area of the base) you need a radius it doesn't give us that but it does give us the circumference.
C= 3.14(2r)
25.12=2r divide each by 2
12.56=r
now use this in the volume formula:
V= 12.56^2(3.14)(66)
V=32,692.86 cubic inches
Just multiply 1000 jumps by 3 to get your answer.
