The center of the dilation is the origin, and the scale factor is 2.
To find the coordinates of the points under this transformation, it is enough to multiply both coordinates of the points X, Y, and Z by 2.
Take a look at the dilation of point Z. To get to Z', both the x and y coordinate of Z must be multiplied by 2.
So, the coordinates are:
X'(8, 0); Y'(6, 4); Z'(4, -4).

Answer:
C
Step-by-step explanation:
The central angle is equal to the arc that subtends it, that is 54°
area of sector = area of circle × fraction of circle
A = πr² ×
= π × 10² ×
= 100π × ( cancel 20 and 100 )
= 5π × 3
= 15π cm² → C
