Question

Write an equation of the circle whose radius is 3 and whose center is (-1.6).

Answer 1

Answer: (x + 1)² + (y - 6)² = 9

Explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²

Given: (h, k) = (-1, 6), r = 3

Input the given values into the equation:

(x - (-1))² + (y - 6)² = 3²

(x + 1)² + (y - 6)² = 9
