Introduction

In this article, we will delve into the world of mathematics and explore the concept of calculating the volume of a spherical object. Specifically, we will be working with a fishing net glass float that is spherical in shape and has a diameter of 10 inches. We will use the value of pi (π) to calculate the volume of the float and provide the final answer in a box, rounded to three decimal places.

What is the Volume of a Sphere?

The volume of a sphere is given by the formula:

V = (4/3) * π * r^3

where V is the volume of the sphere, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the sphere.

Calculating the Radius of the Sphere

Given that the diameter of the sphere is 10 inches, we can calculate the radius by dividing the diameter by 2:

r = diameter / 2 = 10 / 2 = 5 inches

Calculating the Volume of the Sphere

Now that we have the radius of the sphere, we can plug it into the formula for the volume of a sphere:

V = (4/3) * π * r^3 = (4/3) * 3.14159 * (5)^3 = (4/3) * 3.14159 * 125 = 523.598775598

Rounding the Final Answer

To provide the final answer in a box, rounded to three decimal places, we will round the calculated volume to 523.600.

Conclusion

In this article, we calculated the volume of a spherical fishing net glass float with a diameter of 10 inches. We used the formula for the volume of a sphere and the value of pi (π) to arrive at the final answer. The calculated volume is 523.600 cubic inches.

Final Answer

The final answer is: 523.6

Discussion

This problem is a great example of how mathematics can be applied to real-world objects. The concept of calculating the volume of a sphere is essential in various fields, including engineering, physics, and architecture. The use of pi (π) in the formula for the volume of a sphere highlights the importance of mathematical constants in mathematical calculations.

Q&A: Calculating the Volume of a Sphere

Q: What is the formula for the volume of a sphere?

A: The formula for the volume of a sphere is:

V = (4/3) * π * r^3

where V is the volume of the sphere, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the sphere.

Q: How do I calculate the radius of a sphere?

A: To calculate the radius of a sphere, you need to know the diameter of the sphere. The radius is half of the diameter:

r = diameter / 2

Q: What is the value of pi (π) used for in the formula for the volume of a sphere?

A: Pi (π) is a mathematical constant that is used in the formula for the volume of a sphere to calculate the volume. The value of pi (π) is approximately equal to 3.14159.

Q: How do I calculate the volume of a sphere with a diameter of 10 inches?

A: To calculate the volume of a sphere with a diameter of 10 inches, you need to follow these steps:
