Question

The equation of the circle in the first quadrant touching each coordinate axis at a distance of one unit from the origin is.

• A. $x ^ { 2 } + y ^ { 2 } - 2 x - 2 y + 1 = 0$
• B. $x ^ { 2 } + y ^ { 2 } - 2 x - 2 y - 1 = 0$
• C. $x ^ { 2 } + y ^ { 2 } - 2 x - 2 y = 0$
• D. None of these

Answer 1

Answer: (A)

$x ^ { 2 } + y ^ { 2 } - 2 x - 2 y + 1 = 0$

Answer 2

Circle is $x ^ { 2 } + y ^ { 2 } - 2 x - 2 y + 1 = 0$as centre is (1, 1) and radius = 1.
