the approximation of pi to 3.14 is widely known.

this is a rough approximation of the actual cost.

we need a close approximation of the target temperature.

the model provides a reasonable approximation of reality.

the calculation is an approximation, not an exact value.

for a quick estimate, we can use this approximation.

the approximation error was within an acceptable range.

the software offers a good approximation of the original data.

this is a linear approximation of a more complex function.

the approximation algorithm converges quickly to a solution.

it's just an approximation; don't take it as absolute fact.
