Given an arc of a sector is three times its radius, find the angle subtended by

the arc.

The angle subtended by the arc is 171.8873385 degrees (3 radians)

Step-by-step explanation:

The formula of the length of an arc of a sector is L = × 2 π r, where

∵ An arc of a sector is three times its radius

∴ L = 3r

→ Equate the formula of the length of the arc by 3r

∵ × 2 π r = 3r

→ Divide both sides by r

∴   × 2 π = 3

→ Simplify the left side

∵   x = 3

→ Divide both sides by  

∴ x = 171.8873385°

∴ The angle subtended by the arc is 171.8873385 degrees (3 radians)

he has now walked a total of what?

if i know what this is maybe i can
