To solve for \( c \) in the equation \( c = (V49.6)^2 \), we first need to interpret the expression \( V49.6 \).
Assuming \( V \) refers to the square root, we rewrite the expression as follows:
\[ c = (\sqrt{49.6})^2 \]
According to the property of square roots, squaring a square root returns the original value:
\[ c = 49.6 \]
Thus, the solution for \( c \) is:
\[ \boxed{49.6} \]
