A: Find the precise circumference of the trunk and divide by Pi.
B: Cut the tree halfway through and stick a tape measure at the end of the cut (the middle of the tree) XD
Wrap a string around the tree and measure the length. Divide the length by pi (~3.14159); that is an approximation of the diameter (if the tree really was cylindrical. Cut the tree down measure the stump.
To determine the diameter of a tree, measure the circumference of the tree trunk at chest height (about 4.5 feet above the ground) and then divide that measurement by the mathematical constant pi (, approximately 3.14). The result will give you the diameter of the tree.
To properly measure and choose the right size of a Christmas tree foot for your holiday decorations, first measure the diameter of the tree trunk at the base. Choose a tree foot stand that can accommodate a tree trunk of that diameter. Additionally, consider the height and weight of the tree to ensure the stand is sturdy enough to support it.
Most people just measure the circumference and divide by 3.14 (approximate pi) to find the (approximate) diameter.
the diameter of a willow tree is not known on the computer.
Tallest tree is the California redwood, it can reach up to 385 feet in height. The most massive tree is the giant sequoia, trunks measure up to 30 feet in diameter.
Internal diameter.
Diameter of the tree is 2.5 feet (7.85 ft/3.1416)
Internal diameter.
The radius of a circle is half the diameter.
The diameter is the width.
Given an atom with diameter of 100 picometers, the diameter in inches is 4 nano inches.
