What is the cross sectional area of a golf ball?
The area of a circle is pi x r2 So you just have to find the radius of your circle, which is the radius of your golf ball. Then substitute it into the area of a circle formula as above.
What is the cross sectional area of the 4 pipe?
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
How do you find the volume of a trapezium?
A trapezium is a 2D shape; volume it an attribute of 3D shapes. The volume of all trapezia is 0.
A trapezium of area 140 m has parallel sides 10cm apart and one of these sides is 16 cm long find the length of the other parallel sides?
The area of the trapezium cannot be 140 metres since the latter is a length, not an area. Suppose the area is 140 m2 = 1400000 cm2 Suppose the length of the second parallel side is x cm. Area of trapezium = 1/2*(sum of lengths of parallel sides*distance between them) ie 1400000 = 1/2*[(16+x)*10] 280000 = 16+x so x = 279984 cm = 2.79984 kilometres.
What is the area of a trapezium with height 3cm and two parallel lengths of 5cm and 7cm?
Oh, what a happy little question! To find the area of a trapezium, you can use the formula: 1/2 * (sum of parallel lengths) * height. So, for this trapezium with lengths of 5cm and 7cm, and a height of 3cm, the area would be 1/2 * (5 + 7) * 3 = 1/2 * 12 * 3 = 18 square centimeters. Just imagine that beautiful shape on your canvas!
How do you find cross sectional area of cable when you have the lent current and the voltage drop?
cross sectional area of cable * voltage drop
How do you find the volume of cylindrical object?
Volume = cross-sectional area times height
What formula you can use to find the volume of a cylinder?
Find the cross-sectional area of the cylinder (pi x the radius2), the multiply that by the height of the cylinder
How do you find the volume of a cylinder when the diameter and height are given?
Divide volume by height will give you cross sectional area. The cross section of a cylinder is a circle. Area of a circle= π r2 divide your value of cross sectional area by π square root this value and multiply it by 2 that value is diameter.
When a pipe has an outside of diameter 42mm and a bore of 26mm find its cross-sectional area?
The cross-sectional area of a tube is equal to the area of the outer circle minus the area of the bore, so using the formula for area of a circle, we can do the following. A = pi*(42/2)2-pi*(26/2)2 = 272 pi, A = 854.513 mm2
How do you convert sq.ft. to cu.ft.?
You cannot convert sq. ft. into cu. ft. because, sq. ft. is the unit of area and the unit of volume. But if you know the cross sectional area of a cylinder in cu. ft. and its length (or height ) in ft. Then you can find its volume in cu. ft. by multiplying cross sectional area and the ;length (or height).
Which will carry most water 2 small pipes with a radius of 2 and 3 inches or the larger single pipe with a radius of 5 inches?
To start, we will find the cross sectional area of the pipes. Pipe with radius of 2 inches Cross sectional area = PI x radius2 = 12.56 inches2 Pipe with radius of 3 inches Cross sectional area = PI x radius2 = 28.26 inches2 Pipe with radius of 5 inches Cross sectional area = PI x radius2 = 78.5 inches2 As the cross sectional area of the pipe with a radius of 5 inches (78.5 inches2) is greater than the sum of the cross sectional areas of the pipes with radii of 2 inches and 3 inches (40.82 inches2), it can be concluded that the pipe with a radius of 5 inches will be able to carry the most water. (Assuming that all three pipes are the same length).
How do you find the diameter of a tank when you only have the circumference?
the question: a cylindrical tank has a circumference of 13.2, determine the diameter and the cross-sectional area of the tank?
How do you find the height of a cylinder without the height?
It is possible, depending on what you do know. If you have the radius, you can work out the cross sectional area. Measure the volume - by the displacement method. Then volume/cross section = height.
How do you calculate resistance of 70mm2 single core wire?
To calculate the resistance of a single core wire, you will need to know the resistivity of the material the wire is made of, the length of the wire, and the cross-sectional area of the wire. You can use the formula: Resistance = resistivity * (length / cross-sectional area). Plug in the values for the resistivity, length, and cross-sectional area to find the resistance of the 70mm^2 single core wire.
What is the cross sectional area of a golf ball?
The area of a circle is pi x r2 So you just have to find the radius of your circle, which is the radius of your golf ball. Then substitute it into the area of a circle formula as above.
