In order to find the circumference, we first need to find the radius. We have the area, so we can find the radius. We set up this equation:
We begin by dividing both sides by pi.
483.76 =
Next, we take the square root of both sides to get the radius.
r = 22.
Next, we plug this into the formula for the circumference, 2 pi r
So, the circumference of this circle is 138.23 units.

Answer:
Option A
Step-by-step explanation:
Angular velocity of an object is defined by,
Angular velocity (w) =
Here, Δθ = Change in angle of rotation
Δt = Duration or time
In this question Δθ = radians and Δt = 24 seconds
Therefore, angular velocity =
= radians per second
Option A is the answer.
