Formula for circumference: C = 2pi*r

This becomes 201 cm = 2(3.14) r

Divide both sides of this eqn by 6.28:

201
------- = r = 32 cm (approx).

Tigers:-

f(t) = 7(1 + 0.1)^2 where t = number of years

Eagle

g(t) = 15 + 2t

B after ten year number tigers = f(t) = 7(1 + 0.1)^10 = 18

number of eagles = 15 + 10(2) = 35

C when the number of tigers = number eagles the 2 functions will be equal;-

f(t) = g(t) that is:-

7* 1.1^t = 15 + 2t

solve for t
