A circle of radius `5u n i t s` touches the coordinate axes in the first quadrant. If the circle makes one complete roll on x-axis along the positive direction of x-axis , find its equation in new position.

A

`x^(2) = y^(2)+ 20 pi x - 10 y + 10 0 pi ^(2) = 0`

B

` x^(2) + y^(2) + 20 pi x + 10 y + 100 pi ^(2) = 0`

C

` x^(2) +y^(2) - 20 pix - 10 y + 100pi ^(2) =0`

D

None of these
