Raiden Gregory · Answer 1

The circle shifts to the right 3 units and down 8 units. It's radius is 6

Miriam Bruce · Answer 2

The circle has been shifted 3 units to the right and 8 units down.

The radius of the circle would be square root of 36, which is 6

Radius = 6 units

Translation = 3 units horizontally right, 8 units vertically down
