Radius r (12 feet)

Central angle 𝜃 (𝜋/4 radians)

Arc length s: ______ feet



Answer 1

Find the length of the arc on a circle of radius r intercepted by a central angle 𝜃. (Round your answer to two decimal places.)

Radius r (12 feet)

Central angle 𝜃 (𝜋/4 radians)

Arc length s: ______ feet

Arc length C = r x 𝜃 = 12 x 𝜋/4 = 3𝜋 = 9.42 feet.
