Which volume formula or formulas show(s) a joint variation? I V=s^3 II V=pi r^2h III V=Bh I only I,II, and III II and III only III only

## Step 1: Understand joint variation### Joint variation occurs when a quantity varies directly with two or more variables. This means the formula will involve multiplication of multiple variables (e.g., ). ## Step 2: Analyze each formula### - Formula I: does not show joint variation because it involves only one variable, , raised to a power.### - Formula II: shows joint variation because depends on both and , which are multiplied together.### - Formula III: also shows joint variation because depends on both and , which are multiplied together.## Step 3: Identify correct formulas### Based on the analysis, only Formulas II and III exhibit joint variation.
