Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank) (4 points)

Answer 1

Radius is 3 in and height is 9 in. Volume is 3²×9π=81π=254.34 cu in.

Answer 2

The volume is 254.34

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
