the radius of a circular hat is 3.7 inches find the circumference
the answer is 23.236.
Multiply 3.14 times 2 times 3.7
The answer is 23.236, that's it, let's all call it a day.
@yee haw :D is correct.
thx ms.sue /)^-^(\
r = radius so 3.7
pi = 3.14
the formula is pi2r
so 3.14 * 2 * 3.7
3.14 * 2 = 6.28
6.28 * 3.7 = 23.236
Hope this helped!
