Acircle is graphed on a coordinate grid and then reflected across the y-axis. if the center of the original circle was located at (x, y), which ordered pair represents the center of the new circle after the transformation?
a) (x, y)
b) (x, −y)
c) (−x, y)
d) (−x, −y)

Option C. (-x,y)

Step-by-step explanation:

we know that

A point reflected across the y-axis has the following rule

(a,b)> (-a,b)

so

If the center of the original circle was located at (x, y)

then

the center of the new circle after the transformation will be (-x,y)

im alright what do you need

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
