Learn the concept of circumcircle and circumradius of a triangle with examples. Understand the method to construct circumradius and the formula to...
The radius of a circumcircle of an equilateral triangle is equal to (a / √3), where 'a' is the length of the side of equilateral triangle. Does every triangle have an incircle? Every triangle and regular polygon has a unique incircle, but in general polygons with 4 or more sides (...
The formula for the radius of the circle circumscribed about a triangle (circumcircle) is given by $R = \dfrac{abc}{4A_t}$ where At is the area of the inscribed triangle. Derivation: If you have some questions about the angle θ shown in the figure above, see the relationship between ...

To find the area of a circle inside a right angled triangle, we have the formula to find the radius of the right angled triangle, r = ( P + B – H ) / 2. Given
An online calculator to calculate the radius R of an inscribed circle of a triangle of sides a, b and c. This calculator takes the three sides of the triangle as inputs, and uses the formula for the radius R of the inscribed circle given below. ...
To find the length of the radius of the circumcircle of an equilateral triangle with a side length of 6√3 cm, we can use the formula for the circumradius R of an equilateral triangle: R=a√3 where a is the length of the side of the triangle. 1. Identify the side length of the ...
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 circle that passes through all three vertices of the triangle. A right triangle is a tria...
Some Examples of Finding the Circumradius Example 1 Consider aTrianglewith sidesa=5cm, b=6cm, c=7cm, and a circle is circumscribed. Findthe circumradius. Solution Circumradius R= $\dfrac{abc}{\sqrt{(a+b+c)(b+c-a)(c+a-b)(a+b-c)}} $ ...
