The Formula for the Volume of a Right Circular Cylinder: A Mathematical Exploration

In mathematics, the volume of a right circular cylinder is a fundamental concept that has numerous applications in various fields, including physics, engineering, and architecture. The formula for the volume of a right circular cylinder is given by $V=\pi r^2 h$ , where $r$ is the radius of the base and $h$ is the height of the cylinder. In this article, we will explore how to express the volume of the cylinder in terms of a variable $b$ , given that $r=2b$ and $h=5b+3$ .

Understanding the Given Information

Before we proceed with the calculation, let's understand the given information. We are given that the radius of the base of the cylinder is $r=2b$ , which means that the radius is twice the value of $b$ . Similarly, the height of the cylinder is given by $h=5b+3$ , which is a linear function of $b$ . Our goal is to express the volume of the cylinder in terms of $b$ .

Substituting the Given Values into the Formula

To find the volume of the cylinder in terms of $b$ , we need to substitute the given values of $r$ and $h$ into the formula for the volume. We have:

V=\pi r^2 h

Substituting $r=2b$ and $h=5b+3$ , we get:

V=\pi (2b)^2 (5b+3)

Expanding the Expression

Now, let's expand the expression for $V$ :

V=\pi (4b^2) (5b+3)

Using the distributive property, we can expand the expression further:

V=\pi (20b^3+12b^2)

Simplifying the Expression

We can simplify the expression by combining like terms:

V=20\pi b^3+12\pi b^2

In this article, we have explored how to express the volume of a right circular cylinder in terms of a variable $b$ , given that $r=2b$ and $h=5b+3$ . We have substituted the given values into the formula for the volume, expanded the expression, and simplified it to obtain the final result. The volume of the cylinder in terms of $b$ is given by $20\pi b^3+12\pi b^2$ .

The formula for the volume of a right circular cylinder is a fundamental concept in mathematics that has numerous applications in various fields. In this article, we have demonstrated how to express the volume of the cylinder in terms of a variable $b$ , given that $r=2b$ and $h=5b+3$ . This type of problem is commonly encountered in mathematics and physics, and it requires a deep understanding of algebraic manipulations and mathematical concepts.
