Answer: [tex]r = 7[/tex] inches

Step-by-step explanation:

The formula for finding the volume of a cylinder is given as :

[tex]V = \pi r^{2}h[/tex]

substituting the given values , we have

[tex]49\pi = \pi r^{2} (1)[/tex]

Therefore:

[tex]49 = r^{2}[/tex]

take the square root of both sides

[tex]7 = r[/tex]

Therefore :

[tex]r = 7[/tex] inches
