Math Problem Statement

solve for the indicated variable v=1/3pi r squared (h-1);h

Solution

We are given the equation:

v=13πr2(h1)v = \frac{1}{3} \pi r^2 (h - 1)

We need to solve for hh. To do this, follow these steps:

Step 1: Isolate the term involving hh

Multiply both sides by 3 to eliminate the fraction:

3v=πr2(h1)3v = \pi r^2 (h - 1)

Step 2: Divide by πr2\pi r^2

Now, divide both sides by πr2\pi r^2:

3vπr2=h1\frac{3v}{\pi r^2} = h - 1

Step 3: Solve for hh

Add 1 to both sides:

h=3vπr2+1h = \frac{3v}{\pi r^2} + 1

Thus, the solution for hh is:

h=3vπr2+1h = \frac{3v}{\pi r^2} + 1

Here are 5 related questions to deepen your understanding:

  1. How does the formula change if the coefficient 13\frac{1}{3} was different?
  2. What happens to the value of hh if the radius rr increases?
  3. How would you solve for vv in terms of hh?
  4. How does the equation change if the expression inside the parentheses was (h2)(h - 2) instead of (h1)(h - 1)?
  5. What real-world applications might involve using this type of equation?

Tip: Always check if you can simplify the equation early on to avoid complex calculations later.
