The formula for finding the surface area of a hollow cylinder is: 2πrh + 2π(R+r)h, where r is the inner radius, R is the outer radius, and h is the height of the cylinder.
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
Volume = Area * Length The volume of a right circular cylinder is πr2h where r is the radius of the base and h is its height (altitude)
The volume of a cylinder is the area of its base's area times the height (you will prove this in Calculus). Thus the formula you need to use is: pi * radius^2 * height. I will let you do your own homework from there.
2 X Pi X radius X height = area Circumference X height = area (times two if you want inside and outside assuming the walls are of zero thickness)
area of the cylinder base multiplied the height of the 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.
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.
The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume
2πr(h+r)
The volume of a cylinder is its height times the area of its base. And the area of its base is the area of a circular shape.
Surface area of a cylinder = (pi) x (diameter of the circular end) x (length)
