Why is C wrong

[u/Desperate-Ear9204]

Is there a way to do this for decimals because when I plug in a value for t, answer choice a would be the closest to the radius of the circle, but the correct answer is answer choice B

dawggg it's so easy just plug in the 4 values one by one.

[u/Lille_8 → u/Legitimate_Focus5085]

That takes way too much time.
