a) so —> —>
b) For a tolerance of +/- , the Area A can fall in this range: (approx) so the radius can vary over the range cm
or approx. cm so that means the radius can vary approx. cm from the ideal (v = variation from ideal).
c)
x is the independent variable, I'd say it corresponds to 'r' in the above.
f(x) is a function of x, and it corresponds to Area in the above.
a is a constant that x approaches, (30cm)
L is the limit, ( )
The limit is defined such that for 0<|x-p|<, |f(x) - L| < for real and real . My guess is and
