If the area is 72.382mm what is the radius

About 4.8

Step-by-step explanation:

The formula for the area is pi(r^2).

Plugging the area in to the equation, you get 72.382=pi(r^2).

Dividing both sides by pi, you get about 23.04=r^2.

Taking the square root of both sides you get about r=4.8

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
