Below are sample questions representative of the exercises included on this worksheet and related GEO.124 Arc length and sector area skill assessments:

Problem 1Difficulty: Mastery
A drone flies along a circular arc of radius 75 m for 25pi m. What is the area of the sector swept out by the two radii and the flight path?
A625pi square m
B1875pi/2 square m
C1875pi square m
D3750pi square m
Solution & Explanation:Use A = 1/2rs with r = 75 and arc length s = 25pi. The area is 1/2(75)(25pi) = 1875pi/2 square m.
Problem 2Difficulty: Mastery
A circular logo is divided into three sectors with central angles 40 degrees, 80 degrees, and 240 degrees. What is the ratio of their sector areas in that order?
A1:2:6
B2:4:5
C1:3:6
D40:120:240
Solution & Explanation:In the same circle, sector areas are proportional to central angles. The ratio 40:80:240 simplifies to 1:2:6.
Problem 3Difficulty: Mastery
A washer-shaped piece is a 135-degree annular sector. Its outer diameter is 20 cm and inner diameter is 12 cm. What is its area?
A12pi square cm
B18pi square cm
C24pi square cm
D36pi square cm
Solution & Explanation:The outer radius is 10 and inner radius is 6. The area is (135/360)pi(102 - 62) = (3/8)(64pi) = 24pi square cm.
