Question

I need the answer to be proper in simple steps​

Answer 1

Answer:

  a) φ = 4/7

  b) φ = 4

Step-by-step explanation:

The relationship between radius, angle, and arc length is ...

  a = r·φ . . . . . φ in radians

You want to find the angle φ, so you can divide this equation by r:

  φ = a/r

__

a) φ = a/r = (8 cm)/(14 cm) = 8/14

  φ = 4/7 radians

__

b) φ = a/r = (16 cm)/(4 cm) = 16/4

  φ = 4 radians
