Astorage tank holds 115,500 in3 of a chemical. the chemical is dispensed to completely fill 25 identical cylindrical containers, each with a radius of 3.5 in.
what is the height of the cylindrical containers? use 3.14 to approximate pi and express the answer as a whole number

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

The answer is -pie over 2
