This isn't hard at all! The 6 dolls she brought are 20% of her entire collection, right? All you have to do is multiply the 20% by 5 so you can get the amount of dolls to 100%, so
6 x 5 = 30
That's how many dolls there should be.
Formula:
(3.14)r^2
Larger one:
(3.14)(3)^2
28.26 * 13
367.38 in^2
Smaller one:
(3.14)(3)^2
28.26 * 8
226.08 in^2
