1. Question 1

   Q1. The equation of a circle with center (2, -3) and radius 5 is

   • A) (x-2)² + (y+3)² = 25
   • B) (x+2)² + (y-3)² = 5
   • C) (x-2)² + (y+3)² = 5
   • D) (x+2)² + (y+3)² = 25

   Answer: (x-2)² + (y+3)² = 25

   Explanation: Standard circle equation (x-h)² + (y-k)² = r². Subtract h and k from x and y. Radius squared is 25.
