Find the radius of a circle on which a central angle measuring 5 over 6 pi radians intercepts an arc on the circle with a length
ira [324]
Arc length = rθ    [r = radius of the circle, θ = central angle in radians]  ⇒


r= \cfrac{arc \ length}{\theta} =   \cfrac{35 \pi }{ \frac{5}{6} \pi  } = \cfrac{35 \pi *6}{5 \pi } =7*6=42 \ cm

anzhelika [568]

Answer:

2.25

Step-by-step explanation:

Old: 4 in.

New 9 in.

The old length of 6 inches became a new length of 13.5 inches.

Divide the new size by the corresponding old size.

9/4 = 2.25

13.5/6 = 2.25

You see in both cases, the scale factor is 2.25

The scale factor is 2.25
