Using the graph below, select all statements that are true. A. f(4.5)=5
B. f(1.4)=1
C. f(0)=0
D. This is the graph of the greatest integer function.
E. This graph is one-to-one.

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
