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.

first you get the radius of the base. than you do " pi times radius squared


What is the formula for the weight of a cylinder?

density times volume (Pi times radius squared times height)


What is the formula for area for a cylinder?

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.


Formula for surface area of a cylinder?

2 times pi times the radius squared plus 2 times pi times the radius times the height equals surface area of a cylinder :]


What is the height of a cylinder when only given the volume and radius?

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.


Formula to calculate volume of cylinder?

pi x R squared times height where R = radius


What is the formula for a volume of a cylender?

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


What is the formula for the volume of a cylinder?

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


What is the formula for finding the area of a circle and for finding the volume of a cylinder?

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. :)


What is pi times the radius squared times the height?

This is the volume of a cylinder.
