Introduction

In mathematics, the volume of a sphere is a fundamental concept that is used to calculate the amount of space inside a sphere. The formula for the volume of a sphere is given by V = (4/3)πr^3, where r is the radius of the sphere. In this article, we will explore the different options for calculating the volume of a sphere with a radius of 17 and determine which expression gives the correct answer.

Understanding the Formula

The formula for the volume of a sphere is V = (4/3)πr^3, where r is the radius of the sphere. This formula is derived from the concept of integration and is a fundamental concept in mathematics. The formula can be broken down into three main components:

The constant (4/3) represents the proportion of the sphere's volume to its surface area.
The π (pi) represents the ratio of a circle's circumference to its diameter.
The r^3 represents the cube of the radius of the sphere.

Evaluating the Options

Now that we have a clear understanding of the formula for the volume of a sphere, let's evaluate the different options for calculating the volume of a sphere with a radius of 17.

Option A: $\frac{4}{3} \pi\left(17^2\right)$

This option is incorrect because it uses the square of the radius (17^2) instead of the cube of the radius (17^3). The correct formula for the volume of a sphere is V = (4/3)πr^3, not V = (4/3)πr^2.

Option B: $\frac{4}{3} \pi\left(17^3\right)$

This option is correct because it uses the cube of the radius (17^3) in the formula for the volume of a sphere. The correct formula for the volume of a sphere is V = (4/3)πr^3, and this option correctly implements this formula.

Option C: $4 \pi\left(17^3\right)$

This option is incorrect because it omits the constant (4/3) from the formula for the volume of a sphere. The correct formula for the volume of a sphere is V = (4/3)πr^3, not V = 4πr^3.

Option D: $4 \pi\left(17^2\right)$

This option is incorrect because it uses the square of the radius (17^2) instead of the cube of the radius (17^3) and omits the constant (4/3) from the formula for the volume of a sphere. The correct formula for the volume of a sphere is V = (4/3)πr^3, not V = 4πr^2.

Conclusion

In conclusion, the correct expression for the volume of a sphere with a radius of 17 is $\frac{4}{3} \pi\left(17^3\right)$ . This option correctly implements the formula for the volume of a sphere, which is V = (4/3)πr^3. The other options are incorrect because they either use the square of the radius instead of the cube of the radius or omit the constant (4/3) from the formula for the volume of a sphere.

Calculating the Volume of a Sphere with a Radius of 17

Now that we have determined the correct expression for the volume of a sphere with a radius of 17, let's calculate the volume of the sphere using this expression.

V = (4/3)π(17^3) V = (4/3)π(4913) V = (4/3)(3.14159)(4913) V = 20543.88

Therefore, the volume of a sphere with a radius of 17 is approximately 20543.88 cubic units.
