So first we need to find the area of pizza which is pir^2 radius is 9 so 81pi
Now we need to find area of pizza slice triangle amd subtract its area from pizzas area
Triangles area is (9x5)/2 =22.5
So answer is 81pi-22.5 is left
I think its correct
d=18 inches
r=9 inches
A=9×9×π
A=81π
A≈254.34 square inches

A of the rectangle=l×w
or
A=B×h
A= 9×5
A=45 sqaure inches.

254.34-45= 209.34. As a result, there are about 209.34 square inches of pizza that are left over. Hope it help!
