Start with a rod with a square cross section where each side is 2.7716 inches long. From each corner, measure a distance of 0.8118 inches. Cut off the triangular shapes formed at each corner of the square. This will give an octagonal cross section with a 3 inch diameter.
The interior angles of a regular octagon are each 135 degrees.
In most 10 and under age groups, the circumference is 11 inches. That would make the diameter 3.5 inches. From 12 and under until college softball, the circumference is 12 inches. That diameter would be 3.8 inches.
A sphere cannot have a length of 4 inches and a diameter of 3 inches. Make sure you know what shape your question is about!
If you want the area of a circle, and you know the diameter, then: A = pi*r^2, where r is the radius, and is 1/2 the diameter, so pi*(diameter/2)^2 = (pi/4)*(diameter)^2. If you want square inches, then make sure you have the diameter measurement in inches, first.
The diameter is approximately 8 inches depending on make of tire.
pi*radius2 = 1693.14 square inches Make the radius the subject of the above then double for the diameter diameter = 46.430 inches to 3 decimal places
I have started to make Dove cotes bird houses that are octagonal in shape, the roof also joins the walls and narrows at the top also ending in an Octagonal but much smaller
The circumference of a Major League base can vary; not less than 9 inches or more than 9.25 inches. That would make the diameter of the ball vary between 2.87 inches and 2.94 inches.
Well, darling, if the circumference is 23 inches, the diameter would be 23 divided by π, which is approximately 7.32 inches. But hey, who's counting? Just make sure you measure twice and cut once, honey.
pi*32 = 100.53 inches (approx)
Two are needed at each end of the prism
To make a wooden cane, you will need a piece of hardwood, such as oak or maple, that is about 1-1.5 inches in diameter and around 36 inches long. Use a saw to cut the wood to your desired length. Next, sand the wood to smooth out any rough edges. You can also add a finish, such as varnish or stain, to protect the wood and enhance its appearance. Finally, attach a rubber tip to the bottom of the cane to provide traction and prevent slipping.
