Introduction

When it comes to calculating the volumes of three-dimensional shapes, it's essential to understand the relationships between different geometric figures. In this article, we'll explore the relationship between the volume of a cylinder and a cone with the same base and height. We'll delve into the formulas for calculating the volumes of these shapes and provide a step-by-step guide on how to determine the volume of a cone based on the volume of a cylinder.

The Volume of a Cylinder

The volume of a cylinder is given by the formula:

V = πr^2h

where V is the volume, π (pi) is a mathematical constant approximately equal to 3.14, r is the radius of the base, and h is the height of the cylinder.

The Volume of a Cone

The volume of a cone is given by the formula:

V = (1/3)πr^2h

where V is the volume, π (pi) is a mathematical constant approximately equal to 3.14, r is the radius of the base, and h is the height of the cone.

Relationship Between the Volume of a Cylinder and a Cone

Notice that the formula for the volume of a cone is similar to the formula for the volume of a cylinder, but with an additional factor of 1/3. This means that the volume of a cone is one-third the volume of a cylinder with the same base and height.

Calculating the Volume of a Cone Based on the Volume of a Cylinder

Given that the volume of a cylinder is $20 \, \text{ft}^3$ , we can use the relationship between the volumes of a cylinder and a cone to determine the volume of a cone with the same base and height.

Let's start by substituting the given volume of the cylinder into the formula for the volume of a cone:

V = (1/3)πr^2h

Since the cone has the same base and height as the cylinder, we can substitute the values of r and h from the cylinder into the formula:

V = (1/3)π(r^2h)

Now, we can substitute the given volume of the cylinder ( $20 \, \text{ft}^3$ ) into the formula:

V = (1/3)π(r^2h) = (1/3)(20) = 6.67 , \text{ft}^3

However, this is not the correct answer. We need to find the correct expression that represents the volume of a cone with the same base and height as the cylinder.

Finding the Correct Expression

To find the correct expression, we need to analyze the formula for the volume of a cone:

V = (1/3)πr^2h

Since the cone has the same base and height as the cylinder, we can substitute the values of r and h from the cylinder into the formula:

V = (1/3)π(r^2h)

Now, we can substitute the given volume of the cylinder ( $20 \, \text{ft}^3$ ) into the formula:

V = (1/3)π(r^2h) = (1/3)(πr^2h)

Since the volume of the cylinder is $20 \, \text{ft}^3$ , we can substitute this value into the formula:

V = (1/3)(πr^2h) = (1/3)(20) = 6.67 , \text{ft}^3

However, this is not the correct answer. We need to find the correct expression that represents the volume of a cone with the same base and height as the cylinder.
