Write the equation of the circle-radius form given the center C and radius r.

1.C(0,0), r=2

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = (2)²

x² + y² = 4

2.C(0,0), r=6

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = (6)²

x² + y² = 36

3.C(0,0), r=2√3

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = (2√3 )²

x² + y² = 4(3)

x² + y² = 12

4.C(7,-3),r=11

(x - h)² + (y - k)² = r²

(x - 7)² + (y + 3)² = (11)²

(x - 7)² + (y + 3)²  = 121

5.C(-8,0) r=1/2​

(x - h)² + (y - k)² = r²

(x + 8)² + (y - 0)² = (1/2)²

(x + 8)² + y²  = 1/4
