In a circle of radius 6 miles, the length of the arc that subtends a central angle of 3 radians is?

Circle radius, r, = 6 mi. Sector subtends central angle of 3 radians = (3*180/pi)°.
Circle circumference, C, = 2pi*r = 12pi*mi. Arc length of sector = [(3*180/pi)/360]C =
12pi[3*(180/360)/pi]mi = 18 mi.

S = θr
S = 3rad * 6 miles = 18 miles Answer//

Arclen = Radius * angle_(in rads). Some write it as s = rθ
You Are given the radius & angle. Just multiply. Done!

the length of the arc that subtends a central angle of 3 radians
= 3 * length of chord subtended by angle of 60 deg. at the center.

3rad × 180/π = 171.887°
radius = 6 miles
arc length = 12π (171.887/360) = 18 miles

Forumla for length of a circular arc: s = r*theta
s = 6 miles * 3 radians = 18 miles
