Question

The radius of the circle above is 10 in. What is the circumference of the circle? (Use = 3.14. for π)

Answer 1

Circumference of Circle -->
`2\pi r`

• 
  `\pi` = 3.14
• r: length of radius --> 10in

Now compute with the known information plugged into the equation

-->
`2(3.14) * 10) = 6.28*10 = 62.8in^2`

Thus the circumference of the circle is 62.8 square inches.

Hope that helps!
