Circle Sectors and Arc Length Review

What is the area of the yellow shaded sector?

• 23.6 m²

• 11.8 m²

• 62.8 m²

• 117.8 m²

What is the area of the pink shaded sector?

• 12.6 u²

What region of a circle is defined as the region bounded by two radii and their intercepted arc.

• sector

• segment

• arc

• angle

What is defined as the product of the ratio of the measure of the arc divided by 360 and the circumference of the circle?

• arc measure

• sector area

• segment area

• arc length

How does the process for finding the arc length differ from the process for finding the sector area?

• The arc length is a degree while the sector area is labeled in square units.

• The arc length uses π while the sector area does not always use π.

• The arc length and sector area are always equal.

• The arc length requires using the circumference while sector area requires the circle area formula.

How many degrees (to the nearest degree) does the shaded sector's intercepted arc contain?

• 7⁰

• 14⁰

• 26⁰

• 51⁰
