Quizplus · Accepted Answer

We know that the length of an arc, S, on a circle of radius r intercepted by a central angle of θ degrees is given by:

S = (θ/360) * 2πr

Plugging in the given values, we get:

S = (11eb80b1_afdb_183d_a291_c7205d0abfd5_TB8633_11/360) * 2π(4)

Using a calculator, we get:

S ≈ 2.92

Rounding to two decimal places, we get:

S ≈ 11eb80b1_afdb_3f50_a291_bfad2fda400b_TB8633_11 inches

Therefore, the best choice is C.
