Note:I need some serious help, I been stuck on this for a really long time.

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

step-by-step explanation:

4

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 !
