Answer: True; because the distance between centre and any point on circumference is called radius. (ii) A circle has only finite number of equal chords. (v) Sector is the region between the chord and its corresponding arc. Answer: False, the region between the chord and its corresponding arc is called segment.
Q. What is the region between an arc and the two radii?
The region between an arc and the two radii, joining the centre to the end points of the arc is called a sector. Like segments, you find that the minor arc corresponds to the minor sector and the major arc corresponds to the major sector.

Q. What is the region bounded by an arc of the circle and the sides of a central angle?
A sector is the region bounded by a central angle and its intercepted arc, such as the shaded region in Figure 4.3. area of sectorarea of entire circle = sector angleone revolution⇒Aπr2 = θ2π .
Q. What do you call the region bounded by an arc and the chord of the arc?
More formally, a circular segment is a region of two-dimensional space that is bounded by an arc (of less than Π radians by convention) of a circle and by the chord connecting the endpoints of the arc.
Q. Is the region of the circle enclosed by ARC to the Centre by the radii of a circle?
Sector of a circle: A region in the interior of a circle enclosed by an arc on one side and a pair of radii on the other two sides is called a sector.
Q. What is the name of the region of a circle between 2 radius and arc length?
Hint : A sector is the region which lies between an arc and two radii joining the extremities of the arc and the center .
Q. What is the measure of the arc of the sector?
A central angle which is subtended by a major arc has a measure larger than 180°. The arc length formula is used to find the length of an arc of a circle; ℓ=rθ ℓ = r θ , where θ is in radian. Sector area is found A=12θr2 A = 1 2 θ r 2 , where θ is in radian.
Q. What is arc length and sector area?
To calculate arc length without radius, you need the central angle and the sector area: Multiply the area by 2 and divide the result by the central angle in radians. Multiply this root by the central angle again to get the arc length. The units will be the square root of the sector area units.
Q. What is the definition of a Arc?
(Entry 1 of 5) 1 : the apparent path described above and below the horizon by a celestial body (such as the sun) 2a : something arched or curved. b : a curved path the arc of a fly ball.
Q. What are the types of Arc?
Types of arc welding
| Electrode consumption | Welding method |
|---|---|
| Non-consumable (non-fusible) electrode type | TIG welding Plasma welding |
| Consumable (fusible) electrode type | Shielded metal arc welding MAG welding MIG welding Electrogas arc welding (EGW) |
Q. What are the 3 types of Arc?
- Minor Arcs (two capital letters) Arcs that have a degree measure of less than 180 degrees.
- Major Arc (three capital letters) Arcs that have a degree measure greater than 180 degrees.
- Semi Circle (three capital letters) Arcs that have a degree measure equal to 180 degrees.
Q. Which welding is strongest?
TIG welding
Q. What is the definition of minor arc?
A minor arc (left figure) is an arc of a circle having measure less than or equal to ( radians).
Q. What is the measure of arc QS?
The measure of arc QS is (4x – 18)°.
