Butter

The Orville Redenbacher popcorn factory has a tank of artificial butter substitutes, which is 55 feet tall and 18 feet in diameter. How many gallons of artificial butter substitute can the tank contain?

Correct answer:

V =  1871 gal

Step-by-step explanation:

$$\begin{gathered} h=55\text{ft} \\ D=18\text{ft} \\ r=D/2=18/2=9\text{ft} \\ S=\pi \cdot r^2=3.1416\cdot 9^2\doteq 254.469{\text{ft}}^2 \\ {V}_1=S\cdot h=254.469\cdot 55\doteq 13995.7953{\text{ft}}^3 \\ V=V_1\to \text{gal}=V_1:7.48051948\text{gal}=13995.7953:7.48051948\text{gal}=1871\text{gal}=1871\text{gal} \end{gathered}$$
