Problem Statement
Write the equation of the circle with center (−2, 3) and radius 5.
Explanation
The standard form is (x − h)² + (y − k)² = r² for center (h, k) and radius r. Here h = −2 and k = 3, so (x − (−2))² + (y − 3)² = (5)² ⇒ (x + 2)² + (y − 3)² = 25.
Code Solution

(x−h)²+(y−k)²=r² ⇒ (x+2)²+(y−3)²=25
