Question

The volume of a cylinder is 49pi in.cubed and the height of the cylinder is 1 in. What is the radius of the​ cylinder?

Answer 1

Answer:
`r = 7` inches

Explanation:

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

`V = \pi r^(2)h`

substituting the given values , we have

`49\pi = \pi r^(2) (1)`

Therefore:

`49 = r^(2)`

take the square root of both sides

`7 = r`

Therefore :

`r = 7` inches
