<p>okay so i was thinking </p>

<p>the first ripple is x</p>

<p>second ripple x+3
third ripple x+6</p>

<p>difference 2pi(6) (2nd inc in radius ) - 2pi(3) (1st inc in radius) = 6pi</p>

<p>or </p>

<p>so:
Circumference at end of 3rd second = 2pi9
Circumference at end of 1st second = 2pi6 </p>

<p>btw you’re right. just wanna know why I AM worng</p>
