If the radius of a circle is six inches then the diameter is how many feet?
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
Is the largest chord on a circle the diameter of the circle?
Yes, the largest chord of a circle is its diameter.
Half the diameter of a circle?
Half the diameter of a circle is called its radius.
If a circle has a diameter of 60 what is the diameter?
the diameter of a circle that is 60 is 60 radius is 30 the circumference is 188.46
What is the circumference of a circle with a 10 ft diameter?
The circumference of any circle is (pi) x (the circle's diameter).
It a right triangle is inscribed in a circle the the what is a diameter of the circle?
The diameter is the distance across the centre of the circle.
Does a triangle have a diameter?
No, a triangle is defined by its three sides and/or its angels. The diameter is a characteristic of a circle.
When a right triangle is inscribed in a circle will one of the legs of the triangle always be the diameter of a circle?
yes. the leg of the triangle has to be formed different because of the circle
When a circle is drawn through each vertex of a right triangle the triangles hypotenuse will be equal to what?
The length of the circle's diameter
What is a triangle in a circle that is formed by two chords and a diameter?
If a triangle is drawn in a circle with a diameter as the base of the triangle, then the angle opposite that diameter is a right angle. This is an extension of the theorem that the angle which an arc of a circle subtends at the centre of a circle is twice the angle which the arc subtends at the circumference. In the case of a diameter, then the angle subtended at the centre is 180° and thus the angle at the circumference is 90°.
What is true about the diameter of a circle?
It is 1/pi times the circumference. A triangle with the diameter as its hypotenuse and the third point anywhere on the circle is always a right-angled triangle. A quadrilateral with all four corners on a circle is a cyclic quadrilateral. If one of its diagonals is a diameter of the circle, it has two right angles.
When a circle is drawn through each vertex of a right triangle the triangle's hypotenuse will be equal to?
Its diameter.
How would you construct a right triangle given the length of a leg and the radius of the circumscribed circle?
To construct a right triangle given the radius of the circumscribed circle and the length of a leg, begin with two ideas. First, the diameter of the circle is equal to twice the radius. That's pretty easy. Second, the diameter of the circle is the length of the hypotenuse. The latter is a key to construction. Draw your circle, and draw in a diameter, which is the hypotenuse of the right triangle, as was stated. Now set you compass for the length of the leg of the triangle. With this set, place the point of the compass on one end of the diameter (the hypotenuse of your triangle), and draw an arc through the circumference of the circle. The point on the curve of the circle where the arc intersects it will be a vertex of your right triangle. All that remains is to add the two legs or sides of the triangle. Draw in line segments from each end of the hypotenuse (that diameter) to the point where your arc intersected the curve of the circle. You've constructed your right triangle. Note that any pair of lines that is drawn from the ends of the diameter of a circle to a point on the curve of the circle will create a right triangle.
When a triangle with one side length the diameter of a circle is inscribed in that circle does it have to be a right triangle?
Yes. It follows from one of the circle theorems which states that the angle subtended in a semicircle is a right angle.
What size eqiulateral triangle fits into a circle with a diameter of 5.5 inches?
A triangle with sides of 4.76 inches or less.
How many degrees in a circle with a diameter of 5cm?
360. There are 360 degrees in every triangle.
Why is the diameter the longest chord?
A chord is a straight line from one point on a circle's circumference to another. Because the largest straight line distance in a circle is the diameter and the diameter is also a chord, the diameter is the longest chord. Join the endpoints of a given chord to the center of the circle to form an isosceles triangle. The triangle inequality then tells that the length of the chord is less than two radii of the circle, i.e., less than the diameter. See related links.
