25.40
100
55.20
34.80
2
Which of the following equations of a circle has center at (1 , -3) and radius of 5?
(X-1)2+ (y+3)2 = 25
(X+1) - (y+2) = 25
(X-1)2+ (y+3)2 = 5
(X+1)2 + (y+2)2 = 25
3
What is x?
24.5 cm
24.5 m
27cm
23.5 cm
4
What is the equation of the a circle (6,-4) and radius of 8?
(X - 6)2 + (y + 4)2 = 64
(X - 6)2 - (y + 4)2 = 64
(X + 6)2 + (y - 4)2 = 64
(X + 6)2 - (y - 4)2 = 64
