S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
Answer:
It Should Be 32

Because if you add the 20 6 and 6 it gives you 32 hope this helps
A) c = r +5B) 2*c + 4 * r = 130
Substituting A) into B)B) 2 * (r + 5) + 4 * r = 130B) 2 * r + 10 + 4 * r = 130B) 6r = 12020 rabbits and therefore 25 chickens
Double-Check
2 * 25 + 4 * 20 = 130 total legs
