A circle has a radius of 8ft. Find the length s of the arc intercepted by a central angle of π3 radians. Do not round any intermediate computations, and round your answer to the nearest tenth.

8.4ft

Step-by-step explanation:

Formula for calculating the length of an arc is expressed as

is the central angle = π/3 rad

r is the radius of the circle = 8ft

Substituting the values into the formula above we have;

Hence, the length of the arc s is approximately 8.4 ft.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
