Circumference of the smaller circle, using

, is approximately equal to 18.85 (I used the high floating point precision approximation of pi my calculator has in memory, then rounded to 2 decimal points.)
Using the formula

, which in English says "the smaller circle's circumference is equal to 20% of the larger circle's", we can substitute the known value S:

and solve for L:

.
So the larger circle has a circumference approximately equal to 92.5 units.
you have to apply this formula (a+b)(c-d)=ac-ad+bc-bd
-6a^3*b*5a^2+6a^3b*2ab+6a^3b*b+2ab^2*5a^2-2ab^2*2ab-2ab^2*b=
-30a^5*b+12a^4b^2+6a^3b^2+10a^3b^2-4a^2b^3-2ab^3
