Answer:
10.3
Step-by-step explanation:
So first you get the angle of T which is 25 degrees
The you use the law of sine

Then you get s = 10.34763268
Round to nearest tenth
s = 10.3
Volume of a cone: 1/3

r²h
r is the radius (diameter ÷ 2) and h is the height.
Find the radius first using the diameter: 2

÷ 2 = 1.25
Now plug in the numbers into the formula.
1/3

1.25²10 = <span>16.4

The volume of the cone is 16.4 cubic feet.
I think the missing number should be
12.87
