  1. Question 1

    Q1. The equation of the circle with center (0, 0) and radius 4 is

    • A) x² + y² = 16
    • B) x² + y² = 4
    • C) x² - y² = 16
    • D) x² - y² = 4

    Answer: x² + y² = 16

    Explanation: Using circle equation: (x - h)² + (y - k)² = r², where (h, k) = (0, 0) and r = 4, so x² + y² = 16
