Not necessarily. You can still work out the answers in terms of pi.
For example, in a non calc paper, if there’s a circle and the radius of the circle is 4 and you had to find the area…
Area = π x 4²
= 16π
So your answer would be 16πcm²

No problem! Just remember, in that case, the question should say ‘give your answer in terms of pi’.
