The value of pi is the relationship of a circunference to its diameter. For instance, if you have a circle whose circunference is 9.42477 cm, you shall have a diameter of 3 cm. Any measure of a circunference divided by its diameter shall generates the same numeric value, the pi number.
Multiply the diameter by 'pi' .
how do you calculate the circunference of hemisphere?
If the circle's circunference is 128 then radius is 128/2pi = about 20.372 inches
π is the ratio between the diameter and the circumference of a circle so the formula would be : Circumference = π x Diameter or alternatively (since the radius is half the diameter) Circumference = 2π x Radius.

circumference = pi*diameter
The circumference varies on the tree thickness.
More than 92/93 cm of circunference is undesirable for men.
If the circle's circunference is 128 then radius is 128/2pi = about 20.372 inches
Pi ( π ) is the ratio of any circle' s circunference to its diameter.It's an endless number, so usually it is rounded to 3.14.So, to calculate a circunference's length, you have to do:(Diameter)x(Pi (consider it as 3.14))=(Perimeter)Here are some more digits of the Pi:3.14159265358979323846Check more about it on the realted links.
You get a string that can fit around the bowl and wrap the string around it and mark where they overlap. measure the string and there is the circumfrence!
If you know the diameter of a circle, multiply that by pi (approximately 3.14). If you know the radius, multiply it by 2 x pi.
Circunference is equal to 2pi * radius, there for 14 divide by two equal 7 because radius is half of diameter then you will need to put in your calc... 2(3.1416)*7 and the answer will be the circunference. Or you can simply say 14 pi I think the magic word here is "approximate", from which I believe the question hopes you will use the well known approximation for pi (=22/7). So pi times diameter is 22/7 x 14 = 44km
If the lake is a perfect circle the circumference would be 2 pi r, or 2,224.25 feet. Lakes aren't perfect circles so the circumference is probably much larger.
