A nine point circle is constructed by starting off with a triangle. Draw 10 points on the triangle any equal distance from each other, and connect.
No it will meet the starting point, but you can go on the circle to make it never ending.
radius = circumference divided by 2 x pi so 10.99/6.28 = 175 centimetres
outside of the 3 point circle
The line from the center of a circle to a point on the circle is the radius.
radius = circumference divided by 2 x pi so 10.99/6.28 = 1.75 metres
It is the circle's center point
To make a circle using a compass and a ruler, first place the compass point on the paper where you want the center of the circle to be. Adjust the compass width to the desired radius of the circle. Keeping the compass width the same, draw a complete circle by rotating the compass around the center point. Use a ruler to ensure the circle is drawn accurately and smoothly.
The point from which the circle is drawn IS the center.
It is the center of the circle
The radius is the distance between the center of a circle and a point on the circle
The line from the center of a circle to a point on the circle is the radius.
Find the distance of the point from the centre of the circle. If the distance is - less than that radius then the point is inside the circle, - equal to the radius then the point is on the circle, and - greater than that radius then the point is outside the circle.
