The circumference is 175.92918860102841 feet.
The weight of pressure-treated lumber, specifically a 2x6 board, typically ranges from about 2.5 to 3.5 pounds per linear foot, depending on moisture content and the specific treatment process used. For a standard 8-foot 2x6, this translates to approximately 20 to 28 pounds. The weight can vary slightly based on the type of wood and the level of treatment. Always check with the supplier for specific weights relevant to your project.
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.
how much tensile strength of M20 grade concrete at 28 Days
A yard of concrete weighs two tons, so 28 yards is 56 tons.
A concrete sidewalk typically takes about 24 to 48 hours to harden enough for light foot traffic. However, it can take up to 28 days for the concrete to fully cure and reach its maximum strength. Factors such as temperature, humidity, and the mix used can affect the curing time. It's best to avoid heavy loads on the sidewalk until it has fully cured.
Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared
The circumference of a circle with the radius of 28 inches is 175.9 inches. (C = r x 2 x Pi).
pi = 3.1416 ( a constant) Circumference = 2 * pi * radius, so radius = circumference / (2 * pi) So radius = 28 / ( 2 * 3.1416 ) = 4.456 units
Formula of Circumference = 2πr 2πr = 28π 2r = 28 r = 14 The radius is 14
You divide the diameter by two to get the radius (28 / 2 = 14)
Circumference=2diameter(pi) C=2(28)(pi) C=175.92918860102842135390802946365
Circumference = 2 x PI x radius = 28 x PI = (approx) 87.9645943"
It depends on what is meant by 28 yards: diameter? circumference?
It is the name given to the straight line from the centre of a circle to its circumference when that distance is 28 cm.
Multiply the diameter by pi, which is about 3.14.
28 pi cm, about 88 cm
Well, honey, the circumference of a circle is calculated using the formula C = 2πr, where r is the radius. Since you didn't give me the radius, I can't give you the exact circumference. But if the diameter is 56 cm, then the radius would be half of that, which is 28 cm. Plug that into the formula and you'll get your answer.
