What is a segment that contains the center of the circle and has both endpoints on the circle known as?
It is the diameter.
What best explains the circumstances of a circle?
The circumstances of a circle are that it is a perfectly round shape and that its perimeter is better known as its circumference.
Is diameter a chord explain?
If a line segment touches two points on the circle it is called as: 1. secant; if the line extends outside the circle. 2. chord; if the line is present only within the circle. Diameter is a line which satisfies the second condition hence it is a chord. The additional condition for a chord to be known as diameter is that the chord should pass through the center of the circle!
How do you determine the radius of a circle when you only know the arc?
Given an arc or segment with known width and height, the formula for the radius of a circle is:r = (H÷2) + (W2÷8H)Where: W is the length of the chord defining the base of the arc and H is the height measured at the midpoint of the arc's base
What is the length of a circle known as?
The length around a circle is the circumference The length across a circle is the diameter
