56.5
Step-by-step explanation:
Circumference =
C = 3.14(18) = 56.52
Let 
be the random variable for the weight of any given can, and let 
and 
be the mean and standard deviation, respectively, for the distribution of .
You have
Recall that for any normal distribution, approximately 99.7% of it lies within three standard deviations of the mean, i.e.
. This means 0.3% must lie outside this range, 
. Because the distribution is symmetric, it follows that 
.
Also recall that for any normal distribution, about 95% of it falls within two standard deviations of the mean, so
, which means 5% falls outside, and by symmetry, 
.
Together this means
Solving for the mean and standard deviation gives
and 
.
