Question

Arc length, radius & central angels(deg. & rad)

Answer 1

x = 1.6 rads

Explanation:

In radian format:

Length of arc =
`x r` ..........where x is the angle and r is radius.

Here the length of arc is 14 inches and radius given 9 inches

using the formula:

• 
  `xr = 14`

• 
  `x(9) = 14`

• 
  `x = (14)/(9)`

• 
  `x = 1.6` rads
