draw a square within the circle then draw a straight line between the two sets of opposite corners and where those lines cross is where the center of the circle is.
pick ne 3 points on the perimenter of the circle..... join the 1st point to the 2nd wit a straight line & the 2nd point to the 3rd.... bisect these 2 lines with a compass or simply find the midpoint of the lines.... if u hav bisected the lines draw a strange line thru the 2 points where the arcs cross and where the 2 lines meet is the centre point.... if u got the midpoints of the 2 lines just draw a pendicular line from the midpoint of both lines & again the centre is where the 2 lines meet.... (both methods are the same realie only 4 the fact that bisecting is more accurate!!!)

How would you find the diameter of a pizza?
If it's a circular pizza, you would measure across the middle of the pizza, from a point on one side of the circle to a point exactly 180 degress on the the opposite "side" of the pizza.
How can I find the diameter on 12 inches?
A diameter is a property of circular objects. "12 inches" is not a circular object and so cannot have a diameter.
What are the dimensions of a circular garden?
If you want to find the size of your circular garden you will need a scientific calculator to do some sums. here are the methods.The area of the garden is equal to Pi times the square of the radius. To find the radius, measure from the edge of the circle to it's middle point, cutting a slice of cake.The circumference of the garden (the length of it's outer edge) is equal to Pi times it's diameter. To find the diameter, measure the length from one side to the other, cutting through the center point.
When is differentation used in calculus?
