Find the arc length and area of a sector with radius r = 60 inches and a
central angle of 30°

Answer 1

arc length = radius * central angle * PI /180

arc length = 60 * 30 * PI/180

arc length = 10 * PI = 31.14159 inches

Sector Area = Cent angle / 360 * PI * radius ^ 2

Sector Area = 30 / 360 * PI * 60*60

Sector Area = 300 * PI

Sector Area = 942.48 sq inches
