An equilateral triangle is inscribed in a circle, as shown below. What is the area of the triangle? (1) The radius of the circle is 2. (2) The ratio of the radius of the circle to a side of the triangle is 选项: A、A. if statement (1) ALONE is sufficient to answer the ...
This regular triangle has all sides equal, so the formula for the perimeter is: perimeter = 3 × a How to find the radius of the circle circumscribing the three vertices and the inscribed circle radius? circumcircle radius = 2 × h / 3 = a ×√3 / 3. incircle radius = h / 3 =...
To solve the problem, we need to find the distance d from the vertex A of an equilateral triangle ABC inscribed in a circle of radius 20√3 cm to its centroid G. 1. Understand the Circumradius: The circumradius R of an equilateral triangle is given as R=20√3 cm. The formula for ...

Equilateral triangle formulas Letabe the length of the sides,A- the area of the triangle,pthe perimeter,R- the radius of the circumscribed circle,r- the radius of the inscribed circle,h- the altitude (height) from any side. These values are connected by these formulas below: ...
The inscribed circle radius is required to be 1 unit. The three escribed circles that have equal radii must have 3 units each, and the circumcircle of the triangle must have 2 units. All these requirements may seem outlandish. The aim is to teach crucial Geometric principles that Geometric ...
