Question

What is the circumference of a circle with a radius of 10 cm?

Answer 1

The circumference of the circle is `20pi` cm or about `62.8` cm.

Here's how I did it:

Explanation:

The formula for a circumference of a circle is `2pir`, where `r` is the radius. We can plug our known value of the radius (`10` cm) into the formula and solve.

`2pi10 = 20pi` cm or about `62.8` cm.

Hope this helps!
