Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
There are always two angles between two radii of the same circle ... starting at one of them and going each direction to the other one. If you define the angle between them as the smaller of the two angles, then it can be anything between 0° and 180°. If you define it as the larger of the two, then it can be anything between 180° and 360°. If you don't care which of the two angles is measured, then it can be anything between 0° and 360°.
The area of a circle is directly proportional to the square of its radius. If two circles have radii R1 and R2 , then the ratio of their areas is ( R1/R2 )2
180
Divide 360 by 14, then draw two radii in the circle with this number of degrees between them. Then use a compass to mark off 14 equal arcs around the perimeter. Join the points to the centre.

In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.

It is called the central angle. Hope that helped!
A central angle is formed by two radii in a circle that extend from the center to the circumference, creating an angle at the center. The vertex of the angle is located at the center of the circle, and the two sides of the angle intersect the circle at different points. The measure of the central angle is defined by the arc it subtends on the circle's circumference. Visually, it appears as a wedge shape within the circle.
No. A sector is bounded by part two radii and part of the circumference.
A central angle has its vertex at the center of a circle, and two radii form the Arms. Central angle AOC is described as subtended by the chords AC and by the arc AC. An inscribed angle has its vertex on the circle, and two chords form the arms. Inscribed angle ABC is also described as subtended by the chord AC and by the arc AC.
If "the angle" means the angle between two radii at the centre, the answer is no. You need to know the circumference first. Then use radius = circumference divided by 2 x pi.
Inscribed angles and central angles differ in their definitions and the way they relate to a circle. A central angle is formed by two radii extending from the center of the circle to the circumference, while an inscribed angle is formed by two chords that meet at a point on the circle itself. The measure of a central angle is equal to the arc it subtends, whereas an inscribed angle measures half of the arc it intercepts. This fundamental difference affects their geometric properties and applications in circle-related problems.
A circular sector is formed by two radii and an arc. And the angle formed due to the two radii is central angle(Θ). Area of a sector = (Θ/360) πr2.If we divide a circle into seven sectors having equal central angles then the circle is divided into seven equal parts.Angle of the whole circle is 360o. So we should divide the whole angle into 7 equal parts each measuring 360o/7 and then forming the corresponding sectors.
