Volume of a cylinder is given by V = πr^2h
Since the content of the storage tank completely filled the 25 identical cylinders, this means that the volume of the 25 cylinders combined is equal to the volume of the storage tank.
25(πr^2h) = 235,500
πr^2h = 235,500/25 = 9,420
h = 9,420/(3.14 x 5^2) = 9,420/78.5 = 120.
Therefore, the height of the cylinderical containers is 120 in
Answer:
Step-by-step explanation:
Let X be length of life of the participants in the plan.
Given that X is N(68,3.5)
We convert this to standard normal score z using
a) proportion of the plan recipients that would receive payments beyond age 75=
b) proportion of the plan recipients die before they reach the standard retirement age of 65=
c) x for 86% ceased
Area= pi x r^2
hence,
pi x r^2 = 36 x pi
=> r^2=36
=>r= root over 36 = 6
in short...the radius is 6
(x - 4)(2x + 3)
Using foil:
2x^2 + 3x - 8x - 12
Simplify.
2x^2 - 5x - 12 is the product after using FOIL.
11.25 cups of flour
2.5 x 4 = 10
2.5/2 = 1.25
10 + 1.25 = 11.25
