Yes, the radius of a circle is half of the diameter because the diameter is the line segment that passes through the center of a circle. How do you find a radius of a circle from a circumference? Dividing the circumference by 2pi will give the radius of a circle because the circumferenc...
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...
