Question

In a circle with a 103 ft radius, how long is an arc associated with an angle of 3.8 radians?How long is an arc associated with an angle of 3.8 radians?

Answer 1

Question:

Solution:

If the angle is measured in radians then the length of the arc S is given by the following equation:

S = Angle x Radius.

Thus, applying this equation to the data of the problem, we get:

S = 3.8 x 103 = 391.4

Then, we can conclude that the correct answer (round to the nearest tenth) is:

391.4
