Answer:

V=1384.74 cubic units

Step-by-step explanation:

1) Substitute the values into the volume formula for a cylinder which is $V=\pi r^2h\\ V=3.14(7)^29$

2) Using PEMDAS solve for V

3) First, you square 7 to get $V=3.14*49*9$

4) Next, mulitply the three numbers together to get V. $V=3.14*49*9=1384.74$
