Circle outline6/25/2023 The point where the two lines intersect will be the exact center of the circle. Draw a second line crossing the first one, connecting the other two points of the chords. Once you’ve drawn your chords, draw a diagonal line starting at the point where one chord intersects the edge of the circle, then connect it to the opposite point on the chord below. A chord is a straight line that connects any two points on the outer edge of the circle. The easiest way to do this is to draw two parallel chords across the circle. You can also measure the diameter of a drawing of a circle, but you’ll need to find the exact center of the circle to make an accurate measurement. So, if the area of the circle is 25 square centimeters, the diameter would be 2 x √(25/π), or approximately 5.64 centimeters. If you only know the area of the circle, use the formula diameter = 2 x √(area/π). For example, if your circle has a circumference of 23 inches, the diameter would be 23/π, or approximately 7.32 inches. Just divide the circumference by π to find the diameter. You can also find the diameter of a circle if you know its circumference, or the distance all the way around the outside of the circle. For instance, a circle with a radius of 2 cm would have a diameter of 4 cm. If you know the radius of the circle, all you have to do is multiply it by 2 to get the diameter. Depending on what other information you have about the circle, there are a few different ways to calculate the diameter. The diameter of a circle is the distance straight across the circle from one side to the other at its center.
