You don't. You can calculate iits radius and cross-sectional area but its diameter has insufficient information to calculate its length
The diameter would be 14 cm, since the diameter is twice the radius.
If a circle has a diameter of 14, the circumference is: 43.98.
The area of circle that has diameter of 14 centimeters is: 153.9 cm2
diameter = circumference/pi
The radius of a circle is half the diameter.
14
14 cm
The diameter is twice the length of radius, so it is 28 feet.
Calculate the (diameter of the pipe (D) divide by 2) squared X pi * length and this will give you the volume. eg Volume = (D/2)2 X Pi X Length. (or R2 X Pi X Length) (Use 3.14159265359 as an approximation for Pi.) In practice, 11/14 Times Diameter is used in lieu of (R2 X Pi) as a quick and dirty but near enough approximation.
The formula to calculate radius is Pi x Diameter. So, if the radius is 7, the diameter is 14. Then, do 14 x pi (3.14) and your circumference will be 43.96
14 inches.
It is 14.00281721 or about 14 cm
14*14*6 = 1176 square cm
it is 2744 cubic centimetres
* Length: 43.5 ft (13.2 m) * Weight: 24,500 lb (11,110 kg) * Maximum Diameter: 14 ft (4.2 m)
Area = Length * Breadth = 40" * 14" = 560 square inches.
Length: 43.5 ft (13.2 m)Diameter (max): 14 ft (4.2 m)
