OpenStudy (akashdeepdeb):

Circumference of a circle is given by the formula = 2*π*r Where r is the radius of the circle given to you = 20 inches So the circumference = 2 * 3.14 * 20 [Calculate and get your answer! ] :D Understood? :)

OpenStudy (linn99123):

yes :D

OpenStudy (nurali):

formula for circumference is : 2πr the radius is 20, and you are using 3.14 for pi so plug them in: 2(3.14)(20) do the multiplication: 60(3.14) 125.6
