Question : A cone-shaped storage tank's height and radius are 9 feet and 7 feet, respectively. Determine how much liquid the tank can contain. (Take $\pi$ = 3.14)
Option 1: 471 cubic feet
Option 2: 450 cubic feet
Option 3: 435.32 cubic feet
Option 4: 461.58 cubic feet
Correct Answer: 461.58 cubic feet
Solution : The volume $V$ of a cone, where $r$ is the radius and $h$ is the height. $V = \frac{1}{3} \pi r^2 h$ $= \frac{1}{3} \times 3.14 \times (7)^2 \times 9$ $= 461.58$ Hence, the correct answer is 461.58 cubic feet.
