All those points for which the distance is equal to that of the radius of a circle lie on the circle. For example points U and V lie on the circle.Semicircle:Semi means half, so semicircle is half a circle. It is formed by cutting a whole circle along a line segment passing through...
A line segment joining two points on the circle is a chord. In other words, a chord is a segment whose endpoints are on the boundary of the circle. A chord usually divides a circle into two unequal halves unless the chord goes through the center of the circle. The following two red ...
A circle may be defined as a closed curve whose points are all equidistant from a point or the center. If a circle is cut in half, it becomes a semi-circle. These curves are basic shapes used in many applications and can be seen in many objects....
The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples

What is the diameter of a circle (in units) with the center at {eq}(-5, 3) {/eq} and tangent to the line {eq}8 - 2x = 2 {/eq}? Radius of a Circle: We find a circle's radius by finding the distance between the center and the coordinate o...
A The two radii and the chord form an isosceles triangle.x+x+4x=180Simplify:6x=180Divide by 6: x=30Therefore, the diagram should look like this:As we saw in question 6, this portion of the circle is called a "segment," and we find its area by taking the area of the sector minus...
the perimeter of the region is 10π+20.(b) The x-intercepts of the parabola with equation y=10(x+2)(x−5) are −2 and 5.Since the line segment, PQ, joining these points is horizontal, then its length is the difference in the intercepts, or 5−(−2)=7.(c) The slope ...
