Volume of a Cylinder Calculator

WebThe formula for the volume of a cylinder is height x π x (diameter / 2)2, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius2. Visual in the figure below: First, measure the diameter of the base (usually easier than measuring the radius), then measure the height of the cylinder.

WebWe must now make the cylinder's height 2r so the sphere fits perfectly inside. The volume of the cylinder is: π × r2 × h = 2 π × r3. The volume of the sphere is: 4 3 π × r3. So the sphere's volume is 4 3 vs 2 for the cylinder. … WebYou do need to be more specific, the volume of a sphere is V = 4/3 π r^3, it does not need to be related to a cylinder. So if you know the radius, you can calculate the volume. The volume of a cylinder with the same radius and with a height of 2r (since it would be the diameter across) would be V = π r^2 h = 2π r^3.

WebThe sphere and the 1/2 cylinder are combined. The sphere and the cylinder are then added together to give you the equivalent sphere.
