Final Answer: The result of the expression $x^{2}+4$ for $x=3$ is $\boxed{13}$.

Steps

Step 1 ：The problem is asking to substitute the value of x into the expression and simplify. The expression is $x^{2}+4$ and the given value of x is 3. So, we need to substitute 3 for x in the expression and simplify.

Step 2 ：Substitute x = 3 into the expression, we get $3^{2}+4$.

Step 3 ：Simplify the expression, we get 13.

Step 4 ：Final Answer: The result of the expression $x^{2}+4$ for $x=3$ is $\boxed{13}$.
