Answer:
P (−11, 13), Q (−17, −19), R (23, 27)
Step-by-step explanation:
we know that
The reflection of a figure across the x-axis has the following rule
(x,y) -----> (x,-y)
so
P(-11,-13) -----> P(-11,13)
Q(-17,19) -----> Q(-17,-19)
R(23,-27) ----> R(23,27)
Answer:

Step-by-step explanation:
The circle is a flat surface or area limited or closed by a circumference. It is a two-dimensional figure and is formed by making a curve where it will always have the same distance to the center. Its area can be calculated using the following formula:
