question help: post to forum

Explanation:

Step1: Identify the radius and formula

The radius \( r = 10 \). The formula for the circumference of a circle is \( C = 2\pi r \).

Step2: Substitute the radius into the formula

Substitute \( r = 10 \) into \( C = 2\pi r \), we get \( C = 2\times\pi\times10 \).

Step3: Calculate the circumference

\( C = 20\pi \approx 20\times3.14159 = 62.8318 \).

Step4: Round to the nearest tenth

Rounding \( 62.8318 \) to the nearest tenth gives \( 62.8 \).

Answer:

\( 62.8 \)
