The answer depends on what the "36 inch" measures: inside circumference, radius, diameter?
2 1/4 inch is 9/4 inch long pieces, so if pipe is 36 in long then 36/divided by 9/4 is 36 times 4/9 = 16 pieces
The circumference of a 12 cm circle is: 37.7 cm
36
36inch x 36 inch x 36 inch
The diameter is 36/pi
The circumference is: 36*pi = 113.097 inches rounded to three decimal places
Circumference of any circle = 2*pi*radius or diameter*pi
To calculate the weight of an 8-foot long precast concrete culvert pipe with a 36-inch outside diameter and a 4-inch wall thickness, you first determine the pipe's volume. The outside diameter is 36 inches, and the inside diameter is 28 inches (36 - 2 * 4). The volume can be calculated using the formula for the volume of a cylindrical shell. The density of concrete is typically around 150 pounds per cubic foot, so you can multiply the volume by this density to find the weight. The total weight will be approximately 1,200 to 1,300 pounds.
To find the diameter of a circle with a 36-inch circumference, you can use the formula C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter. Plugging in the values, we get 36 = 3.14159 * d. Solving for d, we find that the diameter is approximately 11.46 inches.

Two 18-inch pipes do not have the same capacity as one 36-inch pipe because the flow capacity of a pipe is determined by its cross-sectional area. The area of a circular pipe is calculated using the formula (A = \pi r^2). An 18-inch pipe has a radius of 9 inches, giving it an area of approximately 254.47 square inches each. In contrast, a 36-inch pipe has a radius of 18 inches, resulting in a much larger area of about 1017.88 square inches, meaning the 36-inch pipe can carry significantly more flow than the two 18-inch pipes combined.
Circumference = 2*pi*rr(radius) = diameter/2 = 36 in/2 = 18 inchesCircumference = 2*pi(18 inches)= 113 inches=========
2 1/4 inch is 9/4 inch long pieces, so if pipe is 36 in long then 36/divided by 9/4 is 36 times 4/9 = 16 pieces
Circumference of any circle = 2*pi*radius or diameter*pi
If the radius is 18 feet - then the diameter is 36 feet. The circumference measurement is irrelevant !
circumference of a circle = 2*pi*radius or pi*diameter
