Surface area = Area of rectangular face + Area of top and bottom circles
Area of rectangular face = pi * diameter * height
Area of top or bottom circle = pi * (diameter)2 / 4
So,
Surface area = 3.14 * 2.1 * 0.38 + 2 * 3.14 * (2.1)2 / 4 = 9.43
The total surface area is 9.43, in whatever units you're using (such as inches squared, meters squared, etc.)

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!
How do you find the height of a box given the width depth and surface area?
divide surface area by width Sorry It is a little more complicated than that. Surface area = (2 X length X width) + (2 X length X height) + (2 X width X height) Solve for height Surface area - (2 X length X width) = 2height(length + width) (Surface area - (2 X length X width))/2(length + width) = height
