The equation to represent a possible boundary of the hurricane's eye is (x - 80)² + (y - 26)² = 7.5²
<h3>
Circle Equation</h3>
The standard equation of a circle is given by:
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and r is the radius.
Given that diameter = 15 miles, hence radius = 15/2 = 7.5. Also, center = (80, 26)
The equation of circle is:
(x - 80)² + (y - 26)² = 7.5²
The equation to represent a possible boundary of the hurricane's eye is (x - 80)² + (y - 26)² = 7.5²
