Question

Find the length of each arc. Round your answer to the nearest tenth

Answer 1

52 yd

Explanation:

The formula for arc length is s = rФ, where r is the radius and Ф is the central angle in radians.

Here the central angle is 300° and the radius is 10 yd.

Convert 300° to radians:

π rad

Multiply 300° by the conversion factor ------------

180°

obtaining

(300/180)π = 5.2 rad

Then the arc length is s = rФ = (10 yd)(5.2 rad) = 52 yd
