Answer:
She will need approximate of plastic border
Step-by-step explanation:
we know that
The circumference of a circle is equal to
In this problem we have
substitute
----> exact value of the length of plastic border
assume
---> approximate value of the length of plastic border
The rule we'll use is
p^(q*r) = (p^q)^r
The exponents have been rearranged a bit.
In this case, p = 3.14, q = 159 and r = x, so,
3.14^(159*x) = (3.14^159)^x
This is in the form A^x with A = 3.14^159
