Question 390853: A gardener has a cylindrical planter that has a diameter of 16 inches and is 2 feet deep. What is the approximate number of cubic feet of potting soil that he will need to fill the planter? Answer by solver91311(24713) (Show Source):
You can put this solution on YOUR website!
The volume of a cylinder is the height (depth in this case) times the area of the base. The base is a circle so the area is given by . The trick to this problem is to determine the value of the radius in feet given the diameter in inches.
The radius is half of the diameter, so 8 inches, but this is equal to foot.
Your calculation is then:
And you get to do your own arithmetic. You will have to guess what your textbook or instructor means by "approximate" and round your answer appropriately.
