Calculate as you would the surface of a cylinder who's height is the length of the central line of the pipe bend.
(2*π*r*h)
where:
r is the (external) radius of the pipe
π is the constant 3.14159... and
h is the length of the cylinder or the center-line of the pipe bend
(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
what is the formula to finding the total surface area of a rhomboid?!
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
derivation of surface area of cuboid
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.
To calculate the surface area of a pipe elbow, you can use the formula for the surface area of a curved surface plus the area of the circular ends. For a standard elbow, first, determine the radius (R) and the angle (θ) of the elbow (typically 90° or 45°). The curved surface area can be calculated using the formula: ( A_{curved} = (θ/360) \times 2\pi R \times L ), where ( L ) is the length of the elbow. Add the area of the two circular ends ( ( 2 \times \pi R^2 ) ) to get the total surface area.
The formula for the surface area of an elbow (or 90° angle) is (pi^2 * (radius2^2 - radius1^2) ) / 4. Where pi = 3.14159, radius 2 = the radius from the center to the outside, and radius 1 = the radius from the center to the inside.
(Pi*(Center of elbow - od/2)^2-(pi*(Center of elbow+od/2)^2)÷4)÷100000=0.221 Square Meter
To calculate the area of a 90-degree elbow, you typically focus on the cross-sectional area of the pipe. The area can be found using the formula for the cross-sectional area of a circle: A = πr², where r is the radius of the pipe. Since the elbow maintains the same diameter, you can use the same radius for calculations. If you need the surface area of the elbow itself, you would need to account for its curvature and length, which can be more complex.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.

The formula for the surface area of a sphere is: 4 pi r 2
It depends on the formula that describes the surface itself. "Curved surface area" is not enough information to answer the question.
