Suface area of cone?
Curved surface area of a cone = pi*radiud*length of slant
What is the formula for finding the suface area of a rectangle?
width times height
What is the suface area of a prism?
it is 2(lw)+2(wh)+2(hl)
What is the formula to find the suface area of a cube?
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.
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!
