To start off answering this, you need to look at the first sentence. A number divided by 3 is 4 more than -11. That means that you can start off by using what you are given and bring it down to A number divided by 3 is -7. So -7*3=-21. I don't understand the rest of your question, but this is what I have come up with based on what I have been given.

Answer:
The area of the top of the large cake is 9 pie in2 and that of the small cake is 81 pie in2. The top of the cake has an area equal to 9 times that of the small cake.
Step-by-step explanation:
Area = πr^2
radius of small cake = 6/2 = 3 Inc
radius of large cake = 18/2 = 9Inc
Area of small cake = π3^2
= 9π
Area of large cake = π9^2
= 81π
Ratio = 81π/9π
= 9
