Ans - 2+121=123
x2 - 22x + 121 = (x - 11)2
(2y-11)^2
42 + 79 = 121 (40+70) + (2+9) = = 110 + 11 = 121
1 + 2 + 3 + 4 + 5 + 6 + 100 = 121
121 + 121
121
365 + 121 + 557 = 1043
0.212 + 121 + 11 = 132.212
If you mean: x^2 + y^2 = 121 then the radius is the square root of 121 which is 11
21 + 121 = 142
112 + 121 = 233
48 + 67 + 134 + 121 + 15 = 385
