The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples
Multiplying the radius by 2 will give the diameter of a circle.Parts of a Circle In day-to-day life, many circular shapes are seen and used, for example, wheels, cups and saucers, cricket grounds, etc. In any circle, the center point is the midpoint of a circle. Circular shapes ...

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 area of a circle having a radius ‘r’ (The distance from the centre to a point on the boundary) is given by πr2where π = $\frac{22}{7}$ or 3.14 (approx.) Let us understand it through an example. Suppose we have a circle that has a radius of 7 cm. Its area will be...

"Radius" is the straight line extending from the center of a circle to its perimeter or from the center of a sphere to its surface. e.g., He measured the radius of the circle accurately. Table of ContentsRadius Definitions Radius can describe a range or scope of activity. The grocery st...
The value of the property determines the radius of the circle. When using the property, instead of drawing the usual right corners of the element, a rounded frame with rounded corners will be used according to an arc of a circle with a given radius: Fig.1 - Border-Radius Circle Example....
The radius of a circle is the distance from its center to the circumference, and if you are working on your geometry homework, or designing anything circular, you'll be writing down a little "r" quite frequently, to stand for "radius." It's also the name of one of the bones in your...
The formula to calculate the radius given the area of a circle is: r = √(A ÷π) The radiusrof a circle is equal to the square root of the areaAdivided by pi. For example,let’s calculate the radius of a circle with an area of 12. ...
