Write the equation of each circle.
5. Circle L with center L(4, -3) and radius 5
6. Circle A centered at the origin with radius 6
7. Circle D with center D(3, 3) and radius 2
8. Circle M with center M(0.-2) and radius 9

Answer:

1. 6

2. 5

3. 3

4. 7

5. (x-4)2 + (y+3)2 =25

6. x2+ y2 = 36

7. (x-3)2+(y-3)2 = 4

8. x2 + (y+2)2 = 81

Explanation:

use formula (x-h)2 + (y-k)2 = r2

where (h,k) is center and r is radius
