calculating surface area
area of dish end
(2/3)*base*height
6(pi)l2, where l = length of side
Oh, dude, "S" in the context of area usually stands for "surface area." It's like the total area of all the surfaces of a three-dimensional object. So, if you're calculating the surface area of a cube, you'd be looking at all six sides added together. Cool, right?
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
Formula for calculating the area of sphere is : 4 * pi * r * r
area of dish end
Calculating volume and surface area.
The answer will depend on what information you have.
The formula for calculating the surface area of a prism is SA 2B Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the prism. The angle of the prism does not directly affect the surface area calculation.
The formula for calculating the electric flux () through a closed surface is EdA, where E is the electric field and dA is a differential area element on the surface.
2(l*w)+2(w*h)+2(l*h)=surface area
