The diameter of a circle is 12 ft find the circumference to the nearest tenth

3 answers

Circumference = 2(pi)(r)

r= 1/2(diameter) = 1/2 (12) = 6 ft

Circumference = 2(pi)(6) = 12(pi) = 37.7 ft
Wrong
it is wrong because you have to round.
its not rounding if you don't do anything because 37.7 is the original #
