Question

11) V = tr2h solve for r2​

Answer 1

Answer:

$r^{2}=\frac{V}{\pi h}$

Step-by-step explanation:

To solve an equation for one of its variables do that:

1. Underline the variable
2. Separate it one side and the other terms on the other side
3. Make its coefficient equal to 1

Let us use these steps to solve our question

∵ V = πr²h

→ Underline r²

∴ V = πr²h

→ Take π and h to the other side by dividing both sides by πh

∵ $\frac{V}{\pi h}=\frac{\pi r^{2}h}{\pi h}$

∴ $\frac{V}{\pi h}=r^{2}$

→ The coefficient of r² is 1, so switch the two sides

∴ $r^{2}=\frac{V}{\pi h}$
