Answer:
12,215 ft³
Step-by-step explanation:
The formula for the volume of a cone is:
V = (1/3)(area of base)(height).
Here the height is 9 ft and the diameter of the (round) base is 12 ft.
First we need to determine the area of the base.
If the diameter is 12 ft, then the radius is half that, or r = 6 ft. The area of the base is then A = πr², which in this problem is A = π(6 ft)² = π (36 ft²). Using 3.14 to approximate π, we get A = 4071.5 ft², which we will round u p to A = 4012 ft².
As before, the volume of this statue is V = (1/3)(area of base)(height), which here comes out to:
V = (1/3)(4072 ft²)(9 ft) = 12,215 ft³ (where I have rounded up to the nearest unit).
A mixed number is a combination of a whole number and a fraction. The fraction 9/2 is equal to 4.5. So you would have to find a mixed number in between 4.5 and 5. You could do this by turning 5 into a mixed number, which would be 10/2.
So now you have to find a mixed number in between 9/2 and 10/2. The best way to do this is multiply both numbers so that you can get a wider range of numbers. You would not be changing the end result, you would only be changing the size of the fraction.
I would multiply both mixed numbers by 2, which would get you 18/4 and 20/4. That would mean that a number in between these two mixed numbers is 19/4. (which would simplify to 4.75)
