Question

A central angle θin a circle with a radius of 3.5 centimeters intercepts an arc with a length of 6.3 centimeters.what is the radian measure of θ?enter your answer, as a decimal, in the box.radians

Answer 1

arc length (s) = radius (r) · angle in radians (θ)
  s  = r · θ
6.3 = 3.5 · θ
1.8 = θ
