If I remember correctly, the equation for circumference is C=2r*pi (R representing radius). For this problem, if 2 is your radius 2R would equal 4. Take this number and multiply it by 3.14 (pi) to get your final answer.
The ODE is linear:
Multiplying both sides by gives
Notice that the left side can be condensed as the derivative of a product:
Integrating both sides with respect to yields
Since ,
so that
