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.


How do you find the radius given the chord length?

If you are given a chord length of a circle, unless you are given more information about the chord, you can not determine what the radius of the circle will be. This is because the chord length in a circle can vary from a length of (essentially) 0, up to a length of double the radius (the diameter). The best you can say about the radius if given the chord length, is that the length of the radius is at least as long has half half the chord length.


There are three shapes circle rectangle and square which one has least perimeter?

For a given area a circle has least perimeter. eg Let area = 100 sq cms. For the square or rectangle the perimeter = 40 cms For the circle the radius is square root of 100/3.1416 = 5.64 and the circumference = 2 x radius x 3.1416 = 35.44 cms


Find the equation of a circle if the circle is tangent to the line -x y40 and the center is on the line x 2y30?

The equation of a circle is equal to: (x - a)2 + (y - b)2 = r2 Where (a, b) is equal to the center of the circle and r = radius. To understand more why this is the equation of a circle, think of a circle with a known center point (a,b). A circle, by definition, is the set of all points an equal distance from a given point (the center). That distance is also known as the radius. So if only we had some formula to calculate the radius, we would have our equation. Luckily we do. In your circle, imagine a right triangle with the hypotenuse being the radius (wikipedia has a good picture of this at http://en.wikipedia.org/wiki/Circle). Using the pythagorean theorem we have a formula for calculating the radius. Remember that the theorem states that: a2 + b2 = c2 Where a and b are the lengths of the two sides of the right triange adjacent to the right angle and c is the hypotenuse. For a circle with a center point at the origin, the length of the two sides a and b are simply x and y; howver if the center is not at the origin the length of each adjacent side is (x-a) and (y-b) (again draw the circle and triangle out or refer to the wikipedia drawing to better see this). Since c = radius, we now can substitute in and get: (x - a)2 + (y - b)2 = r2 Which we know is the equation of a circle In this problem, we don't know the exact center point or radius yet, we only know the equations of lines that intersect the center and are tangent to the circle. From my memory, this problem needs at least one more piece of information (the radius) before it can be solved. If someone else knows how to do this without the radius, please have at it; otherwise (to the poster) double check to make sure the problem you have did not specify a radius.


Where can Great Harvest be located?

Great Harvest Bread cannot be within a 15 mile radius of another bakery due to territorial measures. In theory, Great Harvest Bread makes their building the focal point and draws a circle to enclose at least a 10 mile radius.


How do you draw the Arctic Circle?

The Arctic Circle is an imaginary line on globes and charts at about 66.5°N latitude. Locations north of the Arctic Circle can experience at least one 24-hour period of "night" during the winter. At the North Pole, this becomes 6 months of daylight and 6 months of night. To "draw" the Arctic Circle, make a circle centered on the North Pole, about 2600 kilometers (1616 miles) in radius.


What is the big circle on a football pitch?

This circle is used so that other players on both teams (other than the 2 players in the centre doing the kick off) must stand at least 10 yards away from the centre spot where the ball starts off at the kick off. It is a circle so that it can easily be seen where 10 yards is, because 10 yards is the radius.
