Answer:
x² + y² = 4
Step-by-step explanation:
We need to write the standard equation of circle with , centre (0,0) and radius 2 unit . The Standard equation of the circle ⭕ is ,
=> ( x - h)² + (y -k)² = r²
=> ( x -0)² + (y-0)² = 2²
=> x² + y² = 4 .
• Hence the equation of the circle is x² + y² = 4.
