Answer:
Step-by-step explanation:
The formula for a circle of radius r centered at (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...
(x -2)^2 +(y -(-1))^2 = 4^2
(x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A

Answer:
Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm
Step-by-step explanation:
In triangle Δ XYZ ,
A is the mid point of XY
B is the midpoint of YZ
C is the mid point of XZ
AY = 7
BZ =8
XZ = 18
The mid - point theorem states that,
The segment formed by connecting two mid - points of a triangle is parallel to the third side and half as long
AY = 7 then BC = 7 cm
BZ = 8 then AC = 8 cm
XY = 18 then AB = 9 cm
Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm
