1. radius = 7 ft, central angle = 18°
find arc length.

2.2 ft ( to 1 dec. place )

Step-by-step explanation:

The arc length is calculated as

arc = circumference × fraction of circle

     = 2πr ×

     = 2π × 7 ×

     = 14π ×

     = ≈ 2.2 ft

29 is the correct answer

step-by-step explanation:

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.
