Answer and Step-by-step explanation:

If 10 is the given radius, then we can plug it into the circumference formula.

C = 2πr

C = 2π(10)

C = 20π

Now use a calculator to evaluate 20π.

You should get: 62.83185307179586476925286766559

Now, round to the nearest tenth (aka, the first decimal place after the decimal.

C ≈ 62.8

That is your answer.
