The length of a chord that passes through the center of a circle is the diameter of the circle.
4*pi
circle diameter minus center of pitch cirlce raius
Pi x Diameter = CircumferencePi = 3.14...
The circumference of a cirlce that has a diameter of 3 inches would be about 9.42 inches
pi times radius or diameter equals are of a cirlce
No, it has infinitely many lines of symmetry - any diameter.
You multiply the diameter by Pi, that is 3.14159 (to the nearest 5th decimal). circumf. = dia. x Pi.
1 - There are no edges. 2 - There is only 1 face. 3 - Pie x radius squared = the diameter of a cirlce
no
cirlce
Assuming that cirlce = circle and raduis = radius, the answer is 452 sq metres.
Multiply the diameter by (pi), or the radius by (2 pi). If you have a drawing of the circle, and the center is marked, you can measure the radius and the diameter. Just lay your ruler across the circle, and make sure that it touches the center. If the center isn't marked, then it won't be that easy.
