A circle doesn't have a surface area because it is a 2D object. The area of a circle is = pi r2. if you mean the surface area of a sphere it is = 4 pi r2
the formula in finding the area is AREA=(LENGTH)(WIDTH) (HEIGHT) A=L X W X H) The total area of the net is the same as the surface area of the original. By working out the area of each part of the net and adding them together you get the surface area of the original object.
There must be a typo in this question, "Why does the formula for finding the surface area of arectangular prism is helpful?" What does that even mean?
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
S=6e2
