The area of the original circle is pi times r squared, so 3.14 x 3 squared = 28.26.

If she doubled the area of the circle, that area would be 28.26 x 2 = 56.52

So now pi times r squared will = 56.52

Divide 56.52 by pi to get r squared:
56.52/3.14 = 18
So your answer is 18pi units squared, the last answer
