Question 1044030

recall: a circumference a {{{circle}}} formula is {{{C=2r*pi}}} where {{{r}}} is a {{{radius}}} and constant {{{pi=3.14}}}

since you need diameter {{{d}}}, recall that {{{d=2r}}}; so, a circumference a {{{circle}}} formula could be written as {{{C=d*pi}}}

if the floor of a birdcage is a {{{circle}}} with a circumference of about {{{47.1}}} inches, than the diameter of the birdcage floor is

{{{47.1=d*3.14}}}

{{{d=47.1/3.14}}}.......convert decimals into whole numbers

{{{d=4710/314}}}

{{{d=15}}}-> so, the length of the diameter is {{{15}}} inches
