Could you show the circle so we can solve this? we can’t solve it if you don’t show the area of the circle.
<em>V = 120 in^3</em>
<u><em>Here is why:</em></u>
The volume formula for a pyramid is:

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.
The area formula for a triangle is:

Plug in the numbers.

A = 45
Now we have found the area of B, we can plug it into the volume formula for the pyramid.

V = 120 in^3
-x+5y=20
5y=x+20
12y=2x+60
6y=x+40
x+20+y=x+40
-x from each side:
20+y=40
-20 from each side:
y=20
-x+5*20=20
-x+100=20
-100 from each side:
-x=-80
x=80
y=20
x=80
Hope this helps :)
They are acute angels cause there smaller than 90
The answer is 200 because you multiply 20x12 you get 200
