The formula for calculating development surface area of a truncated cone is Avr = π [s (R + r) + R^2 + r^2]. The solution is area (A) subscript r where r is the radius of the top of the truncated cone. In this formula R stands for the radius of the bottom of the cone and s represents the slant height of the cone.
The answer will depend on what information you have.
The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.
Length x Width x Height = surface area
A quadrilateral does not have a surface area because it is not a voluminous figure.
Surface area of a sphere = 4*pi*radius2
To calculate the surface area of a truncated pyramid, you first take the surface area of each side. That would be the base time the straight height. If it is a 4 side pyramid with equivelant sides, multiply that answer by 4.
The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
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.
