The volume of a sphere is a fundamental concept in mathematics, particularly in geometry. It is a crucial aspect of understanding the properties of three-dimensional objects. In this article, we will delve into the calculation of the volume of a sphere with a given radius and explore the significance of rounding the result to the nearest tenth of a cubic inch.

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

Calculating the Volume of a Sphere with a Radius of 41 Inches

To calculate the volume of a sphere with a radius of 41 inches, we can plug the value of the radius into the formula:

V = (4/3) * π * (41)^3

Using a calculator or a computer program to evaluate the expression, we get:

V ≈ 268,923.59 cubic inches

Rounding the Result to the Nearest Tenth of a Cubic Inch

Since we are asked to round the result to the nearest tenth of a cubic inch, we need to examine the decimal part of the result. In this case, the decimal part is 0.59, which is greater than 0.5. Therefore, we round up to the nearest tenth, resulting in:

V ≈ 268,923.6 cubic inches

Significance of Rounding the Result

Rounding the result to the nearest tenth of a cubic inch is a common practice in mathematics and engineering. It helps to simplify complex calculations and provides a more manageable and interpretable result. In this case, rounding the result to the nearest tenth of a cubic inch gives us a more precise estimate of the volume of the sphere.
