The answer is 120.1 in
The volume of the cylinder (V1) is
V1 = π · r² · h (r - radius, h - height)
The volume of the storage tank (V) is the volume of 25 cylindrical containers:
V = 25 · V1 = 25 · π · r² · h
It is known:
V = 115500 in³
π = 3.14
r = 3.5 in
h = ?
V = 25 · π · r² · h
⇒ 115500 = 25 · 3.14 · 3.5² · h
115500 = 961.625 · h
⇒ h = 115500 ÷ 961.625 = 120.1 in
C) Line a increases more rapidly than line B
volume for the glass 2= 3.14*2.5^2*6/3 = 39.25 cubic cm
60-39.25 = 20.75
glass 1 holds 20.75 cubic cm
height is 20.75 = 3.14*2^2*h
20.75 = 12.56*h
h = 20.75 / 12.56 = 1.65 round to 1.7 centimeters
3.7 units
7.4 divided by 2 ((radius is half of a diameter))
