What is the slope of the line that passes through the points shown in the table?

slope = 2

Step-by-step explanation:

We can find the slope using the following formula

m = (y2-y1)/(x2-x1)

   = (1 - -1)/(2 -1)

   = (1+1)/(2-1)

   = 2/1

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 !
