HELP! QUESTION IS ATTACHED BELOW.

Answer 1

• x² + y² = 16

Explanation:

The radius of the smallest circle is 2 as per the given equation.

The radius of the second circle is 2√2 as the half-diagonal of the square with side of 2.

The radius of the largest circle is 2√2*√2 = 2*2 = 4 units (same logic as above)

The equation for the largest circle is:

• x² + y² = 4² ⇒ x² + y² = 16
