Find points on circumference of circle
WebApr 8, 2024 · 3. Find the circumference of a circle if the radius is 36 cm. (use π = 3.14). 4. If the circumference of a circle is 120 cm, find the radius of this circle. 5. If the circumference of a circle is 68 cm, find the radius of this circle. Basic Components of Circle. 1. Centre of the circle: The center of a circle is the center point in a circle ... WebUse the distance formula to find the length of the diameter, and then divide by 2 to get the radius. Then find the midpoint of the diameter which will be the center of the circle. Now you have the coordinates of the center and the radius and that is all that is necessary to write the standard equation of the circle.
