Piping Engineers Must Be Check

Where L = L Length of side
So if L = 5 cm
Then Area = 5 x 5 = 25 cm²

Where,
L = Length
B = Width
If L = 10 mm, And B = 6 mm
Then, Area = 10 x 6 = 60 mm²

3. Circle:

Where D = Diameter of the circle

Same way we can find out area of quarter of circle

Where D = Diameter of Greater Circle
d = Diameter of Smaller Circle

Where B = Base of Triangle
H = Height of Triangle
5. Cylinder:

where H = Height of Cylinder
D = Diameter of Cylinder

In square block; length, width and height are equal, so

2. Rectangular Block:

Where
L = Length
B = Width
H = Height

Volume of Cylinder = Cross Section Area x Length of Cylinder

Where
D = Diameter of the Cylinder
H = Length of Cylinder

Volume of Triangle Block = Cross Section Area of Triangle x Length (Area of Right Angle Triangle = 1/2 B H)

Where
B = Base of Right Angle Triangle
H = Height of Right Angle Triangle
L = Length of Right Angle Triangle
