To solve the formula \( h = rm \) for \( r \), we need to isolate \( r \) on one side of the equation. This can be done by dividing both sides of the equation by \( m \).
Step 1: Given Equation
We start with the given equation:
\[ h = rm \]
Step 2: Isolate \( r \)
To solve for \( r \), we need to isolate \( r \) on one side of the equation. We do this by dividing both sides by \( m \):
\[ r = \frac{h}{m} \]
Step 3: Substitute Given Values
Substitute the given values \( h = 10 \) and \( m = 2 \) into the equation:
\[ r = \frac{10}{2} \]
