Let point C be on circle A. If ∠BAC 5 radians and segment BC is 12cm, what is the length of the radius
Genrish500 [490]

Answer:

2.4 cm

Step-by-step explanation:

The formula we would use

S = rθ

Where S = Arc length

θ = central angle in radians

r = radius of the circle or length of the radius.

From the question, we can see that if

If C = a point on circle A

The Segment BC = The arc length of the circle = 12cm

∠BAC = central angle in radians = 5 radians.

Since, S = rθ,

Length of the radius = S/θ

= 12cm/5 radians

Length of the radius = 2.4 cm
