- Q2If an arc is half of a circle, what is it called?A semicircleA sectorA quadrantA segment30s
- Q3What do you call the measure of an arc in degrees?The radiusThe segment areaThe chord lengthThe central angle30s
- Q4How is the length of an arc calculated if the radius of the circle is known?By finding the area of the circle and multiplying by the central angleBy dividing the diameter by the chord lengthBy multiplying the radius by the central angle (in radians)By multiplying the diameter with the sector area30s
- Q5What term describes an arc that is larger than a semicircle?ChordSectorMajor arcMinor arc30s
- Q6Which of the following statements is true about a minor arc?A minor arc always forms a right angle with the radius.A minor arc measures less than 180 degrees.A minor arc is equal to the diameter of the circle.A minor arc measures more than 180 degrees.30s
- Q7How is the measure of a central angle related to its intercepted arc?The measure of the central angle is half of the intercepted arc.The measure of the central angle is double the measure of its intercepted arc.There is no direct relationship between the central angle and the intercepted arc.The measure of the central angle is equal to the measure of its intercepted arc.30s
