Question

The clocks radius is 10m. What is the circumference of the clock

Answer 1

20π or 62.8 roughly

Explanation:

Hello!

The formula for finding the circumference of a circle is 2rπ:

In that case, all we have to do is substitute 10m for our r.

2 × 10 = 20.

So circumference will be 20π.

Using 3.14 for π:

We get that 62.8 is a rough estimate for the circumference.

Really, it's 62.831..... going on forever since π is irrational.

Thus, the answer exactly is
`\boxed{20\:\pi}}`.

Hope this helps!
