Answer:
16π units (in terms of π) or 50.27 units (rounded to tenths place)
Explanation:
The answer depends on how your teacher wants your answer...
So, the formula for circumference is diameter times pi.
So, in this case, it would be 16 x π or just 16π. This answer is in terms of pi.
Now, if your teacher wants a rounded answer, 16 x pi is 50.2654825. Depending on which place your teacher wants to round to, you will either get 50 (whole number), 50.3 (tenths place), 50.27 (hundredths place), or 50.264 (thousandths place).
It really depends on how you are asked to round it.
Hope this helps, let me know if you need help rounding it more!
