Solutions
</span>A storage tank holds 235,500 in³ of a chemical. The chemical is dispensed to completely fill 25 identical cylindrical containers, each with a radius of 5 inches. <span>
To solve this problem we have to use this equation - </span>V = πr²h. We know the radius is 5 and the volume is 235,500³.
Calculations
V = πr²<span>h
</span>235,500³ = (3.14)(5)²)h
235,500<span>³ = (3.14) (25))h
</span>235,500<span>³ = 78.5
</span>
<span>
235,500 </span>÷ 78.5 = h
h = 3000
