Question

If r=7 and h = 9 units, what is the volume of the cylinder. Use 3.14

Answer 1

v= 22/7*7^2*9

= 22/7*49*9

=22*7*9

=1386

Explanation:

Answer 2

V=1384.74 cubic units

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`
