Question

in circle T with m angle STU=50 and ST=3 units, find the length of arc SU. Round to the nearest hundredth.

Answer 1

9514 1404 393

Answer:

arc SU ≈ 2.62 . . . units

Explanation:

The arc length is given by ...

s = rθ

where r is the radius, and θ is the central angle in radians.

arc SU = ST·STU = 3·(50°·π/180°) = 5π/6

arc SU ≈ 2.62 . . . units
