Question

For the following, find the arc length:

(Use \large \pi=3.14 and round your final answer to the hundredths.)




x=_________

Answer 1

x = 10.47

Explanation:

circumference = 2 * 10 * π = 20π

centre angle of a circle (in radiant) = 2π

x : 20π = π/3 : 2π

x = (20π * π/3)/ 2π

x = 10 * π/3

x = 10π/3

x = 10.466667

x = 10.47
