Final answer:
The limit of f(x)=1 as x approaches π is 1, as it is a constant function and does not change with different values of x.
Step-by-step explanation:
The student has asked to calculate the limit of f(x)=1 as x approaches π. The value of f(x) is 1 regardless of the value of x because it is a constant function. Therefore, as x approaches π, the limit of f(x)=1 remains unchanged, and the correct answer is A) 1.
