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).
Answer:
I think its B. because if you put 6/4and reduce it it would be 3/2
Step-by-step explanation:
Answer:
9.5 inches width
Step-by-step explanation:
solve it using the proportion method
height/ width = 5/19
so let the width be x
so if height: width:: height: width
5 : 19 :: 2.5 : x
product of extremes = product of means
5 x x = 19 x 2.5
x= 47.5/5
x= 9.5 inches (width )
