How do you derive of surface area of cylinder?
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!
The formula for the surface area of a cylinder?
Surface area of a cylinder = (pi) x (diameter of the circular end) x (length)
What is the formula of surface area of a rectangle?

2 x Pi x radius x height or length = curved surface area
What is the surface area of a cylinder whose length is 10cm and its height is 3 cm?
If by length you mean diameter then the surface area is 80π cm squared= about 251.327cm squared
Formula of surface area?
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
How can you use the formula for the surface area of a box to find the surface area of a cube?
The surface area of a box, which is a cuboid, depends on its length, width and height. A cube is a special type of cuboid in which the length , width and height are all the same.
How do you prove the formula of area of hollow cylinder?
Surface area of a hollow cylinder = 2*pi*radius*length measured in square units.
