Question

The volume of a cylinder is 8,685.9 cubic ft, it has a diameter of 19.2 ft, find the height of the cylinder. Round to the nearest tenth.

Answer 1

Explanation:

Volume of cylinder = π times r^2 times h (height)

8,685.9 = π times r^2 times h

To find the radius, divide the diameter by 2.

19.2 / 2 = 9.6

8,685.9 = 3.14 x 9.6^2

3.14 x 9.6^2 = 289.38 (estimated)

8,685.9 = 289.38

Divide 289.38 by 8,685.9.

289.38 / 8,685.9 = 0.033316064

I hope this is right?!!
