Radius of a circle is the distance between center of circle and the point on circle. Radius is half of diameter, the longest chord of circle. Circumference is the distance around the circle. Radius formula and equation at BYJU’S.
Circumradius definition: the radius of the circle circumscribed around a triangle. See examples of CIRCUMRADIUS used in a sentence.
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 the P, B and H are the perpendicular, base and hypotenuse respectively of a right angled triangle. where π = 22 /...
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...
