How many diameter and radius are there in a circle?
If you are talking about around the circle (Circumference) then the are about 3.14 diameters and 6.28 radii While if you are talking about just across, the 1 diameter and 2 radii. Hope this Helps ;) Please recommend me :)
Do two radii equal one diameter?
Yes. D = 2R
When is pi used in maths?
WHEN THE TEACHER TELLS YOU THAT YOU NEED TO USE PI...SORRY THAT'S ALL I CAN ANSWER FOR YOU...LATERZWhen you use chords, diameter, and radii in circles
What is the radius of a circle whose diameter is .75?
The diameter is a straight line from one side os the circle, through the centre point, to the opposite side of the circle. The radius is a straight line from one side of the circle to the centre point only. So Two radii add to make one diameter. Hence algebrauically, d = 2r If d = 0.75 Then r = 0.75/ 2 r = 0.375
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.
