To find r, you need to isolate it. pi*r^2*60=18,840. divide 18,840 by 60, then pi, it comes out at 100. Now find the square root to get 10
r=10

Answer:
Ok hi im good at math just let me do this in ten mins ok
Step-by-step explanation:
Given:
The point is (-5,7).
To find:
The image of the given point after 90 degrees counter clockwise rotation.
Solution:
If a point rotated 90 degrees counter clockwise, then
Let the given point is P(-5,7). Using the above rule, we get
Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).
