Apile of sand in the shape of a cone with a diameter that is twice the height. express the volume v of sand as a function of the height h.

Step-by-step explanation:

It is given that the shape of a pile of sand is conical.

Diameter of cone is twice the height.

Let height of cone be h.

Diameter of cone = 2h

Radius of the cone =

It means radius of the cone is h.

Volume of cone is

where, r is radius and h is height of the cone.

Substitute r=h in the above formula.

Therefore, the volume of pile of sand is .

yes

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
