Question

anonymous · Answer

it's C right? thats whAT I GOT

anonymous · Answer

That's what I got too. Circumference is pi times diameter.
12*pi = about 12*3
12*3 = 36

So yeah, about 36 ft.

anonymous · Answer

yeah they have asked for best approximation ..take pi value as 3.14 the answer is 37.68~==38

anonymous · Answer

I guess that should be the answer.
Any approximation of pi is just that, an  approximation.
So, bio's answer is technically right,but I'd argue both answers are true to some extent..

anonymous · Answer

when you have both the options i think better to go with the nearest one
