to find the surface area you have to first find the area of each part then add the areas together.
Entire surface area = (2*pi*72)+(14*pi*11) = 791.681 square units to 3 decimal places The area of each of the circles at the ends is pi times the square of the radius, and the surface area of the tube is the circumference times the height, with the circumference being pi times the diameter. Then add together the three areas (2 times the circle plus the tube). If you forget the equation for the surface area of a tube, imagine cutting the tube along its length (height) and laying it flat. Then what was the circumference of a tube becomes the width of a rectangle.
to find the surface area of the triangle we just need to multiply the length with breath. area=lengthXbreadth
You find the surface area of each of its six faces and add them together.
You will need to find the surface area of each face and add them together.
Generally, the heat transfer area of reference is considered to be the outside surface area of the tube. Therefore, figure the outside diameter of the tube to get the heat transfer area.
To increase surface area
to find the surface area you have to first find the area of each part then add the areas together.
It depends on the surface area of what!
The formula to find the surface area of a parallelogram is Base*Height.
the surface area of a tube is calculated as 2 x 3.1416 x r x h 2 x 3.1416 x 5cm x 50cm = 1570.8cm2
surface area of glass plate
Lenght X width = surface area
The surface-area-to-volume ratio may be calculated as follows: -- Find the surface area of the shape. -- Find the volume of the shape. -- Divide the surface area by the volume. The quotient is the surface-area-to-volume ratio.

The surface area of a hexagon is the same as its area. You will normally need to split the hexagon into triangles, find their area and sum these.
