Circumference is given by
C=2πr
From the information:
r=20 in
thus
C=2×π×20
C=40π inches
We're given the one-sided limit,

Evaluating the limand directly at <em>x</em> = 1 gives the indeterminate from
(sin(1 - 1) - exp(1 - 1) + 1) / ln(1) = 0/0
so we can potentially solve the limit by applying L'Hopital's rule. Doing so gives
