9. What are the coordinates of each vertex of A(-2,2), B(2,5), C(6,3),D(4,-3) is rotated 180° clockwise about the origin? a. A'(-2,-2), B'(-5, 2), C'(-3, 6), D'(3, 4)
b. A' (2, -2), B'(-2,-5), C'(-6, -3), D'(-4,3)
c. A(-2, -2), B' (2,-5), C'16. - 3), D'(4, 3)
d. A' (2, 2), B'(-2,5), C'(-6, 3), D'(-4, -3)

Area of new circle with diameter GX is   π x (GX/2)^2

Step-by-step explanation:

Here G, H, and X are on the same line.  

G is the center of small circle and X is the center of large circle

Let GX be the diameter of new circle, then

Radius = GX/2

Area of a circle of radius r is given by  

A = πr^2

Here the radius of circle with diameter GX is,  r = GX/2

Therefore area of new circle with diameter GX is  A = π x (GX/2)^2
