WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 … WebIn the GeoGebra interactivity below there is a circle with 9 equally spaced points on the edge, and one in the centre. Draw as many different triangles as you can, by joining the centre dot and any two of the dots on the edge. Can you work out the angles in your triangles? You should have found four different triangles with angles of: 40, 70, 70.
