Outside circumference is 38 so 2 x pi x the radius = 38 ie radius = 19/pi which is just over 6 cm.
pi * radius2 * height ( pie = 3.14) ( radius is half the diameter) ( the height is 60cm) multiply them all together you get.............................
Entire surface area = (2*pi*72)+(14*pi*11) = 791.681 square units to 3 decimal places The area of each of the circles at the ends is pi times the square of the radius, and the surface area of the tube is the circumference times the height, with the circumference being pi times the diameter. Then add together the three areas (2 times the circle plus the tube). If you forget the equation for the surface area of a tube, imagine cutting the tube along its length (height) and laying it flat. Then what was the circumference of a tube becomes the width of a rectangle.
We need to know the dimensions of the tube. The diameter AND the length of the tube. It takes o.465 yards per foot of length for a tube 4 feet in diameter. .
That depends on the thickness or diameter of the tube.
(With all due respect) Assuming: 1. That the above mentioned is a tube, and 24" refers to the outer diameter 2. That the "area" in question is if the tube was sliced from top to bottom and laid out flat, forming an oblong shape..... (therefore not the volume of the tube) The area is the circumference of the tube x the length of the tube. Circumference = 24" x pi = 24 x 3.14159 = 75.40" (1.915 m) Length of tube = 12 m Therefore metric area of tube = 1.915 x 12 = 22. 98 sq. m Or in Imperial: 75.4 divided by 12 = 6.28 ft. 12m converted to feet = 39.37 ft. Area of tube = 6.28 x 39.37 = 247.24 sq. ft.
LED tube T8 is much coarser than the LED tube T5 T8 is about 3 cm in diameter ,the diameter of T5 is about 1.5 cm. LED tube T8 Power : 36W (120 centimeters ) 30W (100 centimeters ) 18W (60 centimeters ) LED tube T5 Power : 28W (110 centimeters ) 21w (88 centimeters ) 14W (55 centimeters ) 8W (30 centimeters ) The distinction between T8 and T5 LED tube lamps, and their advantages and disadvantages : The difference between T8 and T5 is the thickness , T8 circumference is 8 cm , T5 circumference is 5 cm . The LED tube T5 has less light decay, longer life, but the lower electro-optic efficiency (the emitted light consuming 1W power ). The LED tube T8 has the more light fades , shorter life, but the higher electro-optic efficiency (the emitted light consuming 1W power). The diameter of LED tube T8 is 24MM LED tube T5 is 16MM in diameter Regular LED tube T8 diameter is 1 inch , 1 inch = 25.4mm, 25.4mm multiply 3.14 = 80mm = 8cm, ie 8 cm .LED tube T5 is 5cm
It depends how big it is. Or, the circumference can be one way of defining how big it is. That is, a tube with circumference 10cm will have a circumference of 10cm. This question belongs to the class of questions characterised by "how long is a piece of string?"

Then what was the circumference of a tube becomes the width of a rectangle.
the surface area of a tube is calculated as 2 x 3.1416 x r x h 2 x 3.1416 x 5cm x 50cm = 1570.8cm2
The esophagus is generally larger in diameter than the trachea. The esophagus, which is a muscular tube that carries food from the throat to the stomach, has a diameter of about 2-3 centimeters, while the trachea, which is the windpipe that carries air to the lungs, typically has a diameter of about 1-2 centimeters. However, their sizes can vary slightly among individuals.
A standard Smarties tube is approximately 4.5 inches tall and 1 inch in diameter. A 20 pence coin has a diameter of about 2.1 centimeters (0.83 inches). Given these dimensions, you can fit around 40 to 45 twenty pence coins in a Smarties tube, depending on how tightly they are stacked.
What tube
The urethra varies in size between males and females. In males, it is typically about 18 to 20 centimeters (7 to 8 inches) long and approximately 6 to 8 millimeters in diameter. In females, the urethra is shorter, averaging about 4 to 5 centimeters (1.5 to 2 inches) long and about 6 millimeters in diameter. Overall, the urethral tube is relatively narrow and serves as the conduit for urine excretion.
Tube is measured by outside diameter, pipe is measured by inside diameter.
The inside diameter of a tube is called the "inner diameter" (ID). It refers to the measurement of the tube's internal space, which is crucial for determining the flow capacity and fitting compatibility with other components. In contrast, the outer diameter (OD) measures the tube's external width.
The medical term for the inner diameter of a tube is "lumen."
