Tap the "Calculate Circle" button, which will calculate the values for the unknown measurements, plus display the formulas and steps the calculator used to solve for them. Full details here! It has been observed that since diameter is twice the radius, the proportion between circumference and diameter is equal to i.e. Straight Line Graphs. To calculate the circumference, you need the radius of the circle: The circumference of a circle is the linear distance of the circle's edge. When the line is bent all the way, it wraps around the complete circle. Click save settings to reload page with unique web page address for bookmarking and sharing the current tool settings, or click flip tool to reverse the tool function with current settings, Switch tool with the current settings for diameter, and calculate circle area, circle radius, sphere volume or sphere surface area instead. In more exact words, it is the segment of a straight line that passes through the center of the circle and ends where it touches two points on the circle. The line which is placed at 180 degrees is a straight line. click button [Geometrical manipulations A 9-inch pizza is an example of a diameter: when a person makes the first cut to slice a round pizza pie in half, this cut is the diameter of the pizza. You can calculate it in the following ways: If you know the radius or diameter of the circle: Or any other variable relative to the circle? Step 2: Now click the button "Solve" to get the diameter. So if C / m = , then C = m . This tool will calculate the diameter of a circle from the circumference, and will convert different measurement units for circumference and diameter. Note that my expertise is in creating online calculators, not necessarily in all of the subject areas they cover. Lines and arcs are precise. It can also be known as a curve, outlined by a point where the distance from a given point remains same as the point changes. It is the same as the perimeter of a geometric figure, but the term 'perimeter' is used exclusively for polygons.

You may use my email to send me "What's New" monthly update. I've started by substituting the "y" value in the circle equation with the straight line equation, seeing as at the intersection points, the y values of both equations must be identical. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are exactly 180 degrees apart. Arc: part of the circumference of a circle, Major arc: an arc that is greater than half the circumference, Minor arc: an arc that is less than half the circumference. So if you have a question about the calculator's subject, please seek out the help of someone who is an expert in the subject.
