Answer:
Step-by-step explanation:
- Center: (h, k) (the coordinate of the middle point)
- r(radius): d(diameter)/2 (can be found by counting the number of units vertically or horizontally)
- Standard form of a circle: (x - h)² + (y - k)² = r²
1.
Center: (-2, 3)
Radius: 10/2 = 5
Standard form/ equation: (x + 2)² + (y - 3)² = 25
Standard form:
(x - (-2))² + (y - 3)² = 5²
(x + 2)² + (y - 3)² = 25
2.
Center: (1, 1)
Radius: 6/2 = 3
Standard form/ equation: (x - 1)² + (y - 1)² = 9
Standard form:
(x - 1)² + (y - 1)² = 3²
(x - 1)² + (y - 1)² = 9
Hope this helps!
