Introduction

In this article, we will explore the concept of calculating the volume of a cylinder, specifically an oil tank in the shape of a cylinder. We will use the formula $V = \pi r^2 h$ to find the volume of the oil tank. The formula is a fundamental concept in mathematics and is widely used in various fields, including engineering, physics, and architecture.

Understanding the Formula

The formula $V = \pi r^2 h$ is used to calculate the volume of a cylinder. In this formula, $V$ represents the volume of the cylinder, $\pi$ is a mathematical constant approximately equal to 3.14, $r$ is the radius of the cylinder, and $h$ is the height of the cylinder.

Calculating the Volume of the Oil Tank

To calculate the volume of the oil tank, we need to use the formula $V = \pi r^2 h$. The oil tank has a diameter of 40 feet, which means the radius is half of the diameter, or 20 feet. The height of the oil tank is 32 feet.

Using the Formula to Find the Volume

To find the volume of the oil tank, we can plug in the values of the radius and height into the formula. We get:

$V = \pi (20)^2 (32)$

This expression can be used to find the volume of the oil tank.

Simplifying the Expression

We can simplify the expression by multiplying the numbers together:

$V = \pi (20)^2 (32)$ $V = \pi (400) (32)$ $V = \pi (12800)$

Calculating the Volume

To calculate the volume, we need to multiply the value of $\pi$ by the product of the radius and height:

$V = \pi (12800)$ $V = 3.14 (12800)$ $V = 40192$

Therefore, the volume of the oil tank is approximately 40192 cubic feet.

Conclusion

In this article, we have explored the concept of calculating the volume of a cylinder, specifically an oil tank in the shape of a cylinder. We have used the formula $V = \pi r^2 h$ to find the volume of the oil tank. The formula is a fundamental concept in mathematics and is widely used in various fields.
