To solve for \( r \) in the proportion
\[
\frac{r}{2} = \frac{56}{8},
\]
you can cross-multiply:
\[
r \cdot 8 = 2 \cdot 56.
\]
Now, calculate \( 2 \cdot 56 \):
\[
2 \cdot 56 = 112.
\]
So, we have:
\[
8r = 112.
\]
Next, divide both sides by 8 to solve for \( r \):
\[
r = \frac{112}{8} = 14.
\]
Thus, the solution is:
\[
r = 14.
\]
\[
\frac{r}{2} = \frac{56}{8},
\]
you can cross-multiply:
\[
r \cdot 8 = 2 \cdot 56.
\]
Now, calculate \( 2 \cdot 56 \):
\[
2 \cdot 56 = 112.
\]
So, we have:
\[
8r = 112.
\]
Next, divide both sides by 8 to solve for \( r \):
\[
r = \frac{112}{8} = 14.
\]
Thus, the solution is:
\[
r = 14.
