If the circle is 12" in diameter

c meaning circumference
2006-09-07 18:03:59 · update #2
I'm guessing that you mean circumference. It's 2πr where π is 3.14159 and r is the radius of the circle.

Any inscribed triangle with its base as diameter forms right angle at the periphery of a circle. Take a piece of paper with a square edge and match the edge exactly at the periphery of the circle. Mark two points where the paper intersects the circle. Draw a line between these two points and you have one diameter. Do it again and you will get second diameter. Intersection of two diameters is the center of the circle.

What does "c" stand for? Circumference? c=3.14 * diameter

C = pi x diameter
C = 22/7 x 12"
C = 37.7"

assume you mean center:
draw any two diagonally opposing lines, it is where they intersect

c=2*22/7*r(radius).....
or
c=2*pie*r..
