Which of the following is not true in determining if two graphs are inverses of each other? the graphs are reflections of each other over the line y = x the graphs are reflections of each other over the x-axis the intersection of the equation and it's inverse will be on the line y = x the x-value and the y-value switch places in every ordered pair

B

Step-by-step explanation:

The first choice is true.

The second is not true.

Third is true.

I think the last is true  (not sure)

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 !
