In all answers there are p, so I guess its \(\pi\)? So you should not write 3.14 instead of it but just keep it.

ok so \[S=4\pi r^2=4\pi3.5^2=4\pi12.25=49\pi\] and taht's your answer, its D you don't need to use 3.14 instead of \(\pi\) because no one asked you. 3.14 is just approximation of \(\pi\) and for math you need the most accurate result.
