Is the Apple iPad A10 MW792LL/A compatible with i phone 11

Not sure just what you mean by “compatible” but yes, the 7th generation 10.2” iPad can run iPadOS 13 and the iPhone can run iOS 13. So all sync features of iCloud and all iOS continuity features will work between those two (Use Continuity to connect your Mac, iPhone, iPad, iPod touch, and Apple Watch - Apple Support).

They will work together just fine. Both devices support the current versions of iOS and iPadOS which is the main thing when it comes to using multiple devices like that.
