So, I would find the total area of the whole things (rectangle and the circle) and then subtract the are of the circle So area of the whole thing is: 9*6=54 Now i need to subtract the circle Area of circle is (pir^2) so pi(3^2)=28.27 Then putting it all together 54-28.27=25.73
pir is just pi*r (r is radius
