Answer:

The volume is 254.34

Step-by-step explanation:

If the cylinder has a diameter of 6 inches, then its radius would be 3 inches.

To know what the height of the cylinder is, the problem tells us that the height is three times the radius. 3 times 3 inches would be 9 inches.

Now we know that

r = 3 inches

h = 9 inches.

The formula to know the volume of a cylinder is:

V = πr²h

V = π(3)²(9)

V = π (9)(9)

V = 81π

V = 81 (3.14)

V = 254.34
