Question

The equation of a circle is x² + y2 = 16. If the circle is translated 2 units up, what is the
equation of the new circle?
(x + 2)² + y² = 16
(x - 2)² + y² = 16
x² + (y + 2)² = 16
x² + (y-2)2 = 16

Answer 1

The equation of the new circle, after being translated 2 units up, is: x² + (y - 2)² = 16.

So x² + (y - 2)² = 16 will be correct
