There really isn't a "why"; that's just how things are. The volume of any solid with a cross-section that does not vary with height is the area of the base multiplied by the height.
The formula for area of a circle is radius squared times pi. The formula for volume of a cylinder is radius squared times pi times height.
For a right cylinder, the formula for volume is quite simple. It is pi times the radius of the cylinder squared times the height of the cylinder.
first you get the radius of the base. than you do " pi times radius squared
The formula for the volume of a cylinder is pi times the radius squared times the height. An easy way to remember the formula is that it is equal to the area of the circle times the height.
2 times pi times the radius squared plus 2 times pi times the radius times the height equals surface area of a cylinder :]

density times volume (Pi times radius squared times height)
The formula for the volume of a cylinder is pi times the radius squared times the height. An easy way to remember the formula is that it is equal to the area of the circle times the height.
2 times pi times the radius squared plus 2 times pi times the radius times the height equals surface area of a cylinder :]
Since the formula for the volume of a cylinder is PI time the radius squared times the height we can calculate the height from the other two values. The height is the volume divide by PI times the radius squared.
pi x R squared times height where R = radius
The formula for working out a cylinder is... pie radius squared times height The pie radius squared works out the area of one of the circle faces, and then multiplying it by the height sort of stretches out the circle face to the cylinder's exact volume
The volume of a cylinder is simply the area of the circular base times the cylinder's height. Volume of a cylinder = ╥ r² h (pi x radius squared x height) ╥ (Pi) ≈ 3.14 r = radius of the base circle, and h = height of the cylinder --- V= pi r squared times height Volume in cubic units = pi*radius2*height
Area of a circle = (pi)r2 [Areacircle = pi time the radius squared.] Volume of a cylinder = (pi)r2h [Volumecylinder = pi times the radius squared times the height.] (This applies to a right circular cylinder. :)
This is the volume of a cylinder.
