Math Problem Statement

The volume of a right cone is defined as V = πr²h/3. What is the simplified form of the expression that represents the cube of this volume, V³? Treat the constant π as you would a variable in your answer.

Solution

The problem in the image asks you to simplify the expression for the cube of the volume of a right cone, given by V=πr2h3V = \frac{\pi r^2 h}{3}. You are to find the simplified form of V3V^3, treating π\pi as a variable.

Step-by-Step Solution

  1. Given Volume Formula: V=πr2h3V = \frac{\pi r^2 h}{3}

  2. Cube the Volume: To find V3V^3, you need to cube the entire expression: V3=(πr2h3)3V^3 = \left(\frac{\pi r^2 h}{3}\right)^3

  3. Apply the Cube: Apply the cube to both the numerator and the denominator: V3=(πr2h)333V^3 = \frac{\left(\pi r^2 h\right)^3}{3^3}

  4. Simplify:

    • The numerator: (πr2h)3=π3×(r2)3×h3=π3r6h3\left(\pi r^2 h\right)^3 = \pi^3 \times (r^2)^3 \times h^3 = \pi^3 r^6 h^3
    • The denominator: 33=273^3 = 27

    So the expression simplifies to: V3=π3r6h327V^3 = \frac{\pi^3 r^6 h^3}{27}

Answer:

The correct simplified form of the expression is: π3r6h327\frac{\pi^3 r^6 h^3}{27}

Based on the options visible in the image, the correct choice would be the one matching this expression.

Here are some related questions you might consider:

  1. What happens if you cube only the radius rr instead of the whole volume?
  2. How would the expression change if you were asked to cube the square root of the volume?
  3. Can you generalize this formula for a cone with a different shape?
  4. What is the effect of changing the height hh on the volume's cube?
  5. How does the unit of measurement affect the cubic volume calculation?

Tip: Always double-check the powers when working with exponents, as it's easy to make small mistakes that can lead to incorrect results!
