Method to find area of a circle is: The area of a circle is its radius squared times pi.
Assuming the pipe has a diameter of 4cm:
radius = 2 cm
Circumference = 12.5664 cm
Area = 12.5664 cm2

What is the cross sectional area of the 4 inch pipe?
A "4-inch pipe" means it has a diameter of 4 inches, which makes the radius 2 inches. Did you ever see the formula pi*r^2 for area of circle? The answer is 4pi where pi=3.1416
How much water does a hose carry that is one and 34 inches in diameter times 100 feet?
I assume you mean 1 and 3/4 inches in diameter. Therefore your cross-sectional area of your hose is pi/4*diameter. You can either leave your diameter in inches or convert it to feet. If you choose to leave you number in inches then you convert 100 ft to 1200 in and multiple 1200*cross-sectional area to get the cubic inches water in the hose. If you choose to convert your diameter to feet then just multiply 100 ft times cross-sectional area to get the cubic ft of water in the hose.
What is the surface area of a prism with a length of 15mm a height of 4 mm and a width of 3mm?
The surface area of a prism is twice the area of the end plus the area of all the sides. For a prism with a polygon cross-section the area of all the sides if given by the perimeter of the cross-section polygon multiplied by the length of the prism. Assuming you have a prism of cross-section that is a rectangle with sides 4 mm and 3 mm, and is 15 mm long (ie it is an oblong), its surface area is: → surface_area = 2 × (4 mm × 3 mm) + 2 × (4 mm + 3 mm) × 15 mm → surface area = 2 × 12 mm² + 14 mm × 15 mm = 234 mm²
How many gallons of water does a 4 in pipe hold per 30 feet?
Area = pi x radius^2 Multiply that answer by 30feet and you have the volume of the pipe.
What is the volume of a prism whose dimensions are 2cm3cm2cm?
A prism must have a minimum of 4 lengths: three (or more) for the cross section and one for the length. There can be fewer cross-sectional measures if more is known about it: for example, one measure would be enough for a regular polygon (you'd need to know how many sides). But there is no such supplementary information.
How much water can 4 feet or 48 inches of the pipe hold?
It depends on the cross sectional area of the pipe.
What is the cross sectional area of the 4 inch pipe?
A "4-inch pipe" means it has a diameter of 4 inches, which makes the radius 2 inches. Did you ever see the formula pi*r^2 for area of circle? The answer is 4pi where pi=3.1416
What is the cross sectional area of an equilateral 1 inch triangle?
An equilateral 1 inch triangle is a plane figure and it does not have a cross-sectional area in any meaningful sense, just an area. Its area is 0.43 = sqrt(3)/4 square inches.
What is the cross-sectional area of a wire if its outside diameter is 0.0625?
Area of cross section of wire= Pi X D2/4=3.14 X (0.0625)2/4=0.0031
Total force exerted on an 8in X 24in area of a boiler plate that has 30 psi acting on it?
the answer is when Pressure acts on a circular area of fluid, so the force exerted by the fluid is. Pfluid =pā A= p Ļ. 4 di. 2 . The cross-sectional area of the pipe wall. A=Ļ. 4
What affects resistance in a circuit?
1.Resistance is dependent on the material.Like wood is insulator(ALMOST infinite resistance). 2.Resistance of a wire having more cross sectional area is less and less cross sectional area is more(i.e. it is inversely propotional to the cross sectional area.) 3.It is more for more length and less for less length. 4. Resistance varies with temprature.For metals like platinum it increses with temprature.
What will happen to the resistance of a wire if it is stretched to increase its length by 4 times?
Assume that the increase in length is achieved by uniform reduction in the cross-sectional area of the wire. Then an increase in length by 4 times will result in the cross sectional area being reduced to a fifth of it original value. This will increase the resistance to five times its previous value.
How many gallons of water are in a 8in pipe 20foot long?
Assuming the pipe is 100% full, find the cross sectional area of the pipe & multiply by length to get volume:CA = (Pi/4)*(diameter2) = (Pi/4)*(0.667 ft)2CA = 0.349 ft2Volume = (CA)*(Length) = 0.349 ft2 * 20 ft = 6.99 ft31 ft3 = 7.4805 gallonsSo, 6.99 * 7.4805 = 52.29 gallons
What is a 2 by 2?
Usually it means a piece of wood/lumber that has a cross-sectional area of 4 square inches, meaning that the cross section is a square of 2 inch side.
What is formula to calculate the area of steel bar?
For surface area of steel bar= pi*diameter*length For cross-sectional area of steel bar= pi (dia)^2/4
How many liters in a 100 millimeter pipe 1 meter long?
Assuming the pipe is 100% full then the volume will be the cross sectional area of the pipe times length. Vol = Pi/4 * (diameter)2 * (length) = (3.14/4)*(0.1 m)2*(1 m) Volume is approximately 0.008 m3. 1 cubic meter is 1000 liters so the volume would be about 8 liters.
Hydraulic diameter of eccentric annulus?
The hydraulic diameter for any cross section is: Dh= 4 * A / Wp Where Dh = hydraulic diameter A = cross sectional area Wp = wetted perimeter
