Answer :
The exact radius of a circle with a radius of 12 inches is 75.4. The formula is 2πr.
we are given
[tex] radius=r=12inches [/tex]
we have to find circumference
so, we can use formula
[tex] C=2\pi r [/tex]
where
r is radius
C is circumference
we are given
r=12
so, we can plug here
[tex] C=2\pi *12 [/tex]
[tex] C=24\pi [/tex]
Since, it is asking for exact circumference
it means it should be without any decimal
so,
[tex] Circumference =24\pi inches [/tex]............Answer
