   Yes, and number 263 should be Integrate[x^3*Sqrt[2*r*x - x^2],x]. I   
   expect Rubi as well as Mathematica to be up to these while you wrote in   
   December (my browser cannot read your current reports):   
      
   Not solved by Rubi   
       261, 262, 263, 525, 527, 697   
   Not solved by Mathematica   
       261, 262, 263, 319, 324, 504, 509, 525, 527, 538
