An arc of length 3.5 miles on a circle with radius 5.5 miles is subtended by a central angle M find the value of M

Answer in radians rounded to hundredths place:

Answer i ndecimal degrees , rounded to tenths place:

Solution

arc length = 3.5 miles

radius = 5.5 miles

arc length = radius * central angle

central angle = arc length / radius

= 3.5 / 5.5

= 0.6363

= 0.63 radians

or 0.6 in decimals
