I know the other answers but what’s a midline

y = 2

Step-by-step explanation:

The midline is the line that the graph is symmetrical about.

It is positioned midway between the maximum and minimum of the graph

Maximum = 3

Minimum = 1

Then equation of midline is

y = = = = 2

That is y = 2

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 !
