2 answers:
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!
