You have uploaded an image containing a list of double integrals with their respective domains of integration. Let me know which problem you'd like assistance with, or if you'd like me to solve a specific one step by step. Alternatively, I can explain a general method for solving double integrals over specified regions.

Here’s how we can proceed:

1. Tell me which specific problem you’d like solved (e.g., #11, #12, etc.).
2. Let me know if you'd like explanations on setting up integration bounds for the regions (D) described.
3. Indicate if you want step-by-step solutions or just the final result.

Please provide a bit more detail, and I’ll get started! 😊
