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 0Â° and 180Â°. If you define it as the larger of the two, then it can be anything between 180Â° and 360Â°. If you don't care which of the two angles is measured, then it can be anything between 0Â° and 360Â°.

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.

central angle A sector

It is called the central angle. Hope that helped!

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.

A circular sector is formed by two radii and an arc. And the angle formed due to the two radii is central angle(Î˜). Area of a sector = (Î˜/360) Ï€r2.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.

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.

A quarter of a circle, formed by two radii forming a right angle at the centre, is called a quadrant.
