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

Step-by-step 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
