Part D ? Question Suppose the cylindrical water tank has a radius of 12 feet. Use this information and the equation modeling the
Wittaler [7]

The volume of the cylindrical water tank that has a length of 20 feet and a radius of 12 feet is about <u>9,048</u> cubic feet.

The correct option is option <em>d</em>;

d. 9,048

<h3>What is the volume of a solid?</h3>

The volume of a solid indicates the amount of space the solid takes at a location.

The formula for finding the volume of the cylindrical tank is presented as follows;

<em>V</em> = π·r²·L

Where;

r = The radius of the tank

L = The length of the tank

From a similar question on the website, we have;

The length of the tank, <em>L</em> = 20 feet

Therefore;

The volume of the tank, <em>V</em> = π × 12² × 20 ≈ 9048

  • The volume of the water tank is about <u>9,048</u> cubic feet
