Math Problem Statement

In the formula for the volume of a cone, V = (1/3)πr^2h, solve for h. Step 1: Multiply both sides of the formula by ___. Step 2: Divide both sides by ___.

Solution

The formula given for the volume of a cone is:

V=13πr2hV = \frac{1}{3} \pi r^2 h

You are asked to solve for hh (the height of the cone).

Step 1: Multiply both sides of the formula by 3

We multiply both sides by 3 to eliminate the fraction:

3V=πr2h3V = \pi r^2 h

Step 2: Divide both sides by πr2\pi r^2

Now, to isolate hh, divide both sides by πr2\pi r^2:

h=3Vπr2h = \frac{3V}{\pi r^2}

Thus, the solution for hh is:

h=3Vπr2h = \frac{3V}{\pi r^2}

  2. How would you solve for the radius rr in the same volume formula?
  3. How does the volume of a cone compare to the volume of a cylinder with the same base and height?
  4. If the volume and radius are known, how can you find the height?
  5. How does changing the height affect the volume of the cone?

Tip:

When solving equations with fractions, multiplying both sides by the denominator helps eliminate the fraction and simplify your work.
