What is the radius of the in circle of the triangle whose sides measure 5 12 and 13 units?

What is the radius of the in circle of the triangle whose sides measure 5 12 and 13 units?

2 units
Therefore the radius of the incircle of a triangle whose sides are 5, 12 and 13 units is 2 units.

What is the radius of the circle inscribed in a triangle with sides 12 35 37?

We have to find the radius of inscribed circle in a triangle with sides of length 12cm , 35 cm and 37 cm. solution : see diagram, let O is the centre of inscribed circle in a triangle ∆ABC. Therefore the radius of circle is 5cm.

How do you find the radius of the incircle of a triangle?

Calculating the radius Its radius, the inradius (usually denoted by r) is given by r = K/s, where K is the area of the triangle and s is the semiperimeter (a+b+c)/2 (a, b and c being the sides).

Which of the following is the correct equation for a circle in the coordinate plane with radius 2?

Correct answer: The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

What is the radius of a circle inscribed in a triangle with sides of length 12 cm 35 cm and 13 cm?

5. Side of a triangle are in the ratio of 12 : 17 : 25 and its perimeter is 540 cm its area. ⇒ Semi–perimeter of the triangle, ∴ The sides are in the ratio of 12 : 17 : 25.

What is the measure of the radius of the circle that circumscribes a triangle whose sides measure 9 40 41?

Question 3 : What is the measure of the radius of the circle that circumscribes a triangle whose sides measure 9, 40, and 41? The radius of the circle that circumscribes the triangle is 20.5.

What is the radius of the incircle of the triangle?

radius of the incircle of triangle= area/semi perimeter. p is half the perimeter, or. P=(18+24+30)/2 = 36. A=square root of (36(36-18)(36-24)(36-30)) =square root of (36*18*12*6) =216 s.cm. radius of the incircle of triangle= 216/36=6cm.

What is the radius of inscribed circle with 12 sides?

Radius found to be => 6 units. Sum of all sides, of this series of Triangles, /12 = Radius of inscribed circle. Radius = 72/12 = 6. Hope that helps. Re; formulae in other answers, thank you each.

What is the radius of the triangle 18/24/30?

This is a right angled triangle. Essentially, this is the basic 3–4–5 right angled triangle with each side 6 times the original. The in-radius of the basic triangle is (3+4 – 5) /2 [Sum of the legs – Hypotenuse]/2 or 1 unit and hence that of the required triangle will be 6*1=6 units. 18,24,30 is a right triangle.

How do you find the radius of a circle in geometry?

Given the side lengths of the triangle, it is possible to determine the radius of the circle. First, form three smaller triangles within the triangle, one vertex as the center of the incircle and the others coinciding with the vertices of the large triangle.
