Because all circles have the same shape, their different measurements are related by a set of simple equations. If you know the radius, diameter, area or circumference of a circle, it is fairly easy to find any of the other measurements. Step 1 Learn the formulas relating radius to circumfe...
The midpoint of a line is the halfway mark of that line. A radius measures the distance from a circle's middle point, or origin, to its surrounding perimeter, also known as its circumference. The midpoint has much in common with the radius, for the midpoint on a diameter measures its...
The radius is the fixed distance from the center of a circle to any point on its circumference. Record the radius of the circle 2. Multiply Radius by Two The radius of a circle always equals half of its diameter, so to find the diameter, multiply the radius by two. For example, if y...
Where is the radius of a circle? The radius of a circle is the line segment from the center of a circle to a point on the boundary of a circle. Is a radius half of a diameter? Yes, the radius of a circle is half of the diameter because the diameter is the line segment that pas...
How to find the radius of a circle with a length on a right triangle? Circumcenter The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of the triangle intersect. It is also the center of the circumcircle of the triangle, which is the c...
How can I find the radius of a circle by knowing two points and its arc length? Do I have to use a numerical method to solve for a trigonometric equation or is there any algebraic or geometric method? Physics news on Phys.org Observing gain-induced group delay betw...

The radius of a sphere or a circle is the distance from its center to its circumference. It is same for any point on the circle.
Radius and Diameter The radius is a line from the center point of a circle to any part of the circle. This is probably the simplest concept related to measuring circles but possibly the most important. The diameter of a circle, by contrast, is the longest distance from one edge of the ...
