Solution to Captivating Circles 5

We can simulate the decrease in size for Jack and Jill with the javascript below:

1. let jack = 1π;
2. let jill = 2.25π;
3. while( jack > 0 ) {
4. jack -= jill * 0.000001;
5. jill -= jack * 0.000001;
6. }
7. console.log(jill);

We will find Jill’s size area to be 6.333 in the console. Divide by π and square root to get Jill’s radius after facing Jack: 1.42.
