Name the line and plane shown in the diagram. I will make you a brainllest

see below

Step-by-step explanation:

The line is AB with ↔ over it

The Plane requires 3 letters not all in a line

The plane name is ABD

y=mx+b

step-by-step explanation:

m slope, b y-intercept

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 !
