For an equilateral triangle where the width of each side is given as w and each angle is 60 degrees:
r = SquareRoot(w^2 - 0.25w^2)
For an isosceles triangle with two angles a and a side between them of length b.
r = 0.5 * b * tan(0.5 * a)

What does a chord look like in math?
When you draw a circle in math, and you draw a triangle inside of it, 2 of the lines should be the radius of the circle, and the third (bottom) line that is not the radius is the chord.
Does a triangle have a radius?
It has at least two radii, the radius of the circle going through the vertices and the radius of the inscribed circle touching all the sides.
The shortest distance from the center of the inscribed circle to the triangle's sides is the circle's?
radius
The shortest distance from the center of the circumscribed circle to the vertices of the inscribed triangle is the circle's radius?

What is the space inside a circle?
Circumference is the outside of the circle and the inside is the are of the circle. And inside of the circle, there is diameter and radius. Radius is from the center point to the edge of the circle and diameter is all the way across.

What does a circle with triangle inside mean?
It is the symbol for Alcoholics Anonymous.
How do you find out if each point is on inside or outside of the circle?
Find the distance of the point from the centre of the circle. If the distance is - less than that radius then the point is inside the circle, - equal to the radius then the point is on the circle, and - greater than that radius then the point is outside the circle.
The shortest distance from the center of the circumscribed circle to the vertices of the inscribed triangle is the circle's radius?
True
An equilateral triangle surrounds a circle of radius 10 cm and is itself surrounded by a larger circle Find the radius of the bigger circle?
Make a sketch of the situation. From a corner of the equilateral triangle draw a radius of the large circle, and from an adjacent side draw a radius of the smaller circle. You should have formed a small right-angled triangle with a known side of 10cm. and known angles of 30o, 60o and 90o. (The interior angles of an equilateral triangle are each 60o.) The hypotenuse is the unknown radius of the larger circle. But since cos 60 = 0.5, it is evident that the hypotenuse is 20cm. long.
How do you measure the area of a circle and why does it work?
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height

An isosceles right triangle is inscribed in a circle Find the radius of the circle if one leg of the triangle is 8 cm?
First you half all the sides, so 4cm, them you multiply by pi, giving the radius as 12pi, or 12.56637061
