Acylinder and a cone have the same volume. the cylinder has radius x and height y. the cone has radius 2x. find the height of the cone in terms of y.

Step-by-step explanation:

The formulas of a volume of

a cylinder:

a cone:

r - radius

h - height

Substitute

The cylinder:

The cone:

The cylinder and the cone have the same volume. Therefore we have the equation:

       divide both sides by πx²

       multiply both sides by 3/4

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
