Question

Write the standard equation of the circle below.

Answer 1

Equation of the first circle is (x - 1)² + (y + 2)² = 9 and that of the second circle is x² + (y + 2)² = 9

Step-by-step explanation:

• Step 1: Given the center of the first circle (h,k) = (1,-2) and radius, r = 3

Equation of the circle = (x-h)² + (y-k)² = r²

⇒ (x - 1)² + (y + 2)² = 9

• Step 2: Given the center of the first circle (h,k) = (0,-2) and radius, r = 3

⇒ x² + (y + 2)² = 9
