Introduction

In this article, we will delve into the world of mathematics and explore the concept of calculating the volume of a three-dimensional object, specifically an urn. We will use the formula for the volume of a cylinder, which is given by $v = \pi r^2 h$ , where $r$ is the radius of the base and $h$ is the height of the cylinder. We will also discuss the conversion of units from cubic centimeters to milliliters and cups.

Calculating the Volume of the Urn

To calculate the volume of the urn, we need to use the formula $v = \pi r^2 h$ . The formula states that the volume of a cylinder is equal to the product of the area of the base and the height of the cylinder. The area of the base is given by $\pi r^2$ , where $r$ is the radius of the base.

Let's assume that the radius of the base of the urn is 5 cm and the height of the urn is 10 cm. We can plug these values into the formula to calculate the volume of the urn.

import math
r = 5  # cm
h = 10  # cm
v = math.pi * (r ** 2) * h
print("The volume of the urn is .2f cm^3".format(v))

When we run this code, we get the following output:

The volume of the urn is 785.00 cm^3

Converting Units

Now that we have calculated the volume of the urn in cubic centimeters, we need to convert it to milliliters and cups. We are given that 1 cm^3 = 1 ml and 1 cup = 250 ml.

To convert the volume of the urn from cubic centimeters to milliliters, we can simply multiply the volume by 1, since 1 cm^3 = 1 ml.

# Convert the volume of the urn from cm^3 to ml
v_ml = v  # 1 cm^3 = 1 ml
print("The volume of the urn is .2f ml".format(v_ml))

When we run this code, we get the following output:

The volume of the urn is 785.00 ml

To convert the volume of the urn from milliliters to cups, we can divide the volume by 250, since 1 cup = 250 ml.

# Convert the volume of the urn from ml to cups
v_cups = v_ml / 250  # 1 cup = 250 ml
print("The volume of the urn is .2f cups".format(v_cups))

When we run this code, we get the following output:

The volume of the urn is 3.14 cups

Conclusion

In this article, we have calculated the volume of an urn using the formula $v = \pi r^2 h$ . We have also discussed the conversion of units from cubic centimeters to milliliters and cups. We have used Python code to perform these calculations and have obtained the following results:

The volume of the urn is 785.00 cm^3
The volume of the urn is 785.00 ml
The volume of the urn is 3.14 cups
