Answer:
301.44
Step-by-step explanation:
Equation for the volume of a cone: V = π

Here, r = 6 and h = 8.
V = π

V = 3.14 *
* 
V = 3.14 * 36 * 
V = 301.44
Or, in exact terms of π, 96π.
There are many ways to solve this. I think the easiest way for this one is to add the equations up.

The you solve that, now that y is gone. You get x=2.
Now plug in x into one of the original equations.

Finish solving, and you get y=8.
The answer is (2,8)
Answer:
i belive it is the first one.
Step-by-step explanation:
When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.
Answer:30 feet.
Step-by-step explanation: 2 doubled is four and in the bigger triangle it says 5. Therefore 12 doubled and a bit more is 30
