The volume we're looking for is the volume of both cones in the figure.
The volume of a cone is .
So, .
<u>Cone 1's variables:</u>
r = 2.6
h = 5
<u>Cone 2's variables:</u>
r = 2.6
h = 3
Now we can just plug and chug!
V = c. 56.6 cubic units
1) the graph is attached.
2) ∠A = ∠A; ∠B = ∠B; ∠C = ∠D; AC/BD = AD/BC = AB/AB
3) The rise from A to D is 4.5; the run from D to B is 9; the slope is 4.5/9 = 1/2.
The rise from C to B is 4.5; the run from A to C is 9; the slope is 4.5/9 = 1/2.
