Answer:
A is 10.0 inches.
B is 35 inches.
Step-by-step explanation:
To find the answers, we can just multiply our original lengths by our scale factor.
Our original width is 8 inches.
This means that our new width, A, will be our old width multiplied by our scale factor.
So:
Similarly, for our length, our old length is 28 inches. This means that our new length is:

Answer:
Therefore radius is 84 units.
Step-by-step explanation:
Given:
arc length = 56 pie
Central angle = θ = 120°
pi = 3.14
To Find:
Radius = r =?
Solution:
If the θ measured in degree then the arc length is given as
Where r = radius, θ = Central angle
On substituting the values we get
Therefore radius is 84 units.
