Use the Formula Lateral Surface Area= 2(pi=3.14)rh
The most general difference is: > The formula for the surface area of anything with a curved surface and edge will involve 'pi'. > The formula for the surface area of anything with only flat surfaces and straight edges won't.
the formula for calculating the surface area of an oval is A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes
To calculate the surface area of an equal tee, you need to find the surface areas of its three cylindrical sections (the two ends and the middle section) and the area of the two circular openings. The formula involves calculating the lateral surface area of the cylinders and adding the area of the circular ends. Specifically, if the radius of the pipe is ( r ) and the length of the sections is ( L ), the total surface area (SA) can be approximated by the formula: [ SA = 2\pi r L + (2 \times \pi r^2) ] This accounts for the lateral surface area of the two vertical sections and the two circular ends.
Formula for calculating the area of sphere is : 4 * pi * r * r
The answer will depend on what information you have.

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.
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.
