Can someone please help me with#2,#5,and #9?I'm not sure how to find the answer.

You have to substitute a value to the x variable (0,1,2,3, etc) and then solve for the y value and place those points on the graph and make a line outlining each x,y.

Hope this helps :)

Comment if you need more help or if it is wrong :) :)

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 !
