The circumference of a circle can be found with this equation:

C = 2[tex]\pi[/tex]r


"r" is the radius, which is half of the diameter.

The diameter is 20.

20 ÷ 2 = 10

Your radius is 10. Now that you know the radius, you can plug it into the equation:


C = 2[tex]\pi[/tex]r

C = 2[tex]\pi[/tex](10)  Multiply 2 and 10 together

C = 20[tex]\pi[/tex]


Your circumference is:

20[tex]\pi[/tex] inches  or  62.8318530718 inches(you should round it if you want lol)
