Question
What is the equation of the circle with center (-3.2, -2.1) and radius 4.3?
Solution
The equation of a circle is given by the formula (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius.
Given the center of the circle as (-3.2, -2.1) and radius as 4.3, we can substitute these values into the formula.
So, the equation of the circle is:
(x - (-3.2))² + (y - (-2.1))² = (4.3)²
Simplify to:
(x + 3.2)² + (y + 2.1)² = 18.49
