Hint: The rule of the 45-45-90 triangle is that both sides are x and the hypotenuse is x√2.
x = 5√2
To find the hypotenuse you multiply x by √2.
5√2 (√2)
5√4
5 (2)
10
The hypotenuse is 10.
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
