Answer: The answer is (2, 2).
Step-by-step explanation: The given system of equations is

We are to find the co-ordinate pair that is the solution for the above system of equation.
Multiplying the second equation by 2 and adding to the first equation, we have

and

Thus, the co-ordinate pair is (2, 2).
Your answer is 150.72.
First, plug in the radius and height into the equation. V=1/3pi*4^2*9
Next solve. 3.14 x 16 x 9 = 452.16
Then you need to divide 452.16 by 3 to get 150.72
The answer will be 3 over 2 which mean 3/2
