Part 1: Use the information rounded to write the standard form equation of each circle.
1. Center: (-2, 9), Radius: 8

2. Center: (-6, 9/2), Radius: 10

3. Center: (15, -10), Radius: 1

1. (x+2)² + (y-9)² = 64

2. (x+6)² + (y-)² = 100

3. (x-15)² + (y+10)² = 1

Step-by-step explanation:

Please see attached picture for full solution.

1. (x + 2)² + (y - 9)² = 64

2. (x + 6)² + (y - 9/2)² = 100

3. (x - 15)² + (y + 10)² = 1

Step-by-step explanation:

Circle:

(x - h)² + (y - k)² = r²

1. Center: (-2, 9), Radius: 8

(x - -2)² + (y - 9)² = 8²

(x + 2)² + (y - 9)² = 64

2. Center: (-6, 9/2), Radius: 10

(x - -6)² + (y - 9/2)² = 10²

(x + 6)² + (y - 9/2)² = 100

3. Center: (15, -10), Radius: 1

(x - 15)² + (y - -10)² = 1²

(x - 15)² + (y + 10)² = 1
