the perimiter =D
to find the perimiter you just add up all the sides....Perimiter is the same for every figure.
Run a piece of string round the edge and then measure it
The perimeter of a circle is called it circumference, "C". To calculate it, multiply its diameter by the constant, pi. Pi is roughly equal to 3.14159265. So, let's say you have a circle with a 10-foot diameter. Then C=10 x 3.14159265 = 31.42 (rounded off).
base times height minus half of the perimiter base times height minus half of the perimiter
2 * pi * r
circumference
The perimeter of a circle is its circumference
the perimiter =D
No,Circumference is like the perimiter and Area is the whole circle.
It depends what shape you are trying to find. If it is a circle, use the following:C = DpiCircumference = Diameter x PiTake the diameter of the circle, or twice the radius, and multiply it by pi, which is ~3.14If it is any other shape, just add up the sides if they are given.
The perimeter is pi*r + 2r = 92.6 cm
perimeter of a circle = circumference = pi x diameter perimeter = 3.1416 x 12 = 37.7 cm
Add up the sides.
to find the perimiter you just add up all the sides....Perimiter is the same for every figure.
Add together the 4 sides
To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
