The perimeter of a circle is called the circle's "circumference". It's the distance an ant must walk
on the curved line in order to get back to where he started walking from.
The diameter of the circle is the distance across it through the center. It's the longest line
you can draw that stays completely inside the circle.
The radius of the circle is half of the diameter. It's the distance from the center to any point
on the circle.
The circumference if the circle is (pi) times (the diameter).
The circumference is also (2 pi) times (the radius).
(Pi) is approximately 3.14159 26535 89792 . The decimal never comes out even.
It's also OK to use ( 22/7 ) for pi. That puts you within 0.1% of the correct answer.
2 * pi * r
The perimeter of a circle is its circumference
the perimiter =D
No,Circumference is like the perimiter and Area is the whole circle.
multiply all of the sides than that is your answer
I'm sorry, but i don't know =/.
Add the four sides.
to find the perimiter you just add up all the sides....Perimiter is the same for every figure.
C = (pi)/d or c = 2(pi)r.
The formula for finding the perimiter of a rectangle is add up all of its sides
The perimeter is pi*r + 2r = 92.6 cm
